Not only do I disagree with this statement, but it seems to contradict itself. The following points can be made:
(1) If ultimately all savings are translated into investments (regardless of the capital gains rate) then how is it good macro economics to reduce capital gains rates to zero? Reducing capital gains rate cannot increase investment if all savings are investments regardless?
The savings rate is not constant. It is upward sloping with interest rates: people save more when interest rates are higher. Of course, there are also many other dynamics, but the point is that reducing capital gains tax improves the risk adjusted returns on investments, so it increases demand for capital, which increases interest rates, and encourages more savings.

(2) There is no actual evidence in the historical record that reducing capital gains rates helps the economy. Virtually all the most prosperous times in US history were when the capital gains rate was significantly higher than it is now.
In something as complicated as an economy, you can get direct historical evidence for only the clearest of signals. At the end of the day, we will probably never have empirical evidence. Also, its clear that capital gains clearly has a bigger effect on risk adjusted returns at low interest rates than at high interest rates. So its a bigger issue now than in 1970.

(3) In fact there are other arguments against reducing capital gains rate. Currently a great deal of effort is put forward to "convert" wages into capital gains, often using accounting tricks (like carried interest). This effort doesn't help the economy, but it does help very wealthy people reduce their taxes. Much of what goes on in investing is a zero-sum game, where one investor "wins" and another "loses" and the companies they are investing in see little to no effect. Because of inflation and a generally growing economy there are more "winners" than "losers" so it's better than the casino in that sense but I don't see this really driving economic growth. In fact we have "lost" a great number of smart and talented individuals to the financial sector, where they are doing things that do not help our economy (and arguably some that hurt, like the type of thing Bain Capital does shutting down profitable businesses), because it's easier to make more money and pay lower taxes in this sector. If I'm a business owner I may well have a choice to operate my business (receiving business profits taxed as wages) or liquidate my business (receiving a one-time big capital gain) and the lower capital gains taxes are relative to wage taxes the more likely I am to do this... to the detriment of my employees and quite possibly the local economy in general.
Higher equity prices make it cheaper for companies to raise capital, either by issuing shares, or because a larger equity buffer lowers the risk premium on bond issues. Shutting down profitable businesses can often be best, if you have more productive ways to deploy that capital.

(4) The claim that it is "better for labor" if capital gains rates are low is highly dubious. Right now capital gains are sucking up a higher percentage of corporate profits and labor is getting a lower percentage. Would reducing taxes on capital gains (so they are more appealing) help this? Suppose the government is going to spend $1B to employ more people; how could it be more efficient to spend this money reducing taxes for investors (who don't work for a living and are already well off) than to spend this money directly employing people? Sure, maybe the investor will invest the money rather than stashing it under a mattress, and maybe that investment will be the type that creates jobs at a reasonable rate rather than just playing the "wall street poker game" against other zillionaires, and maybe those jobs will be created in this country instead of somewhere else... but surely it is more efficient to just create jobs directly?
Lower capital gains would certainly lower labour share. I think I made this point? However, it will also improve productivity and lower prices. Wages have been falling for decades, yet its incontrovertible that we are better off than ever before despite this, as prices have generally fallen further.

(5) In fact technology is often a driver of increasing wealth inequality. Many formerly important jobs are no longer necessary. We need far fewer people working assembly lines because of robotics, we need far fewer paralegals because of expert systems, we will need far fewer taxi drivers if self-driving cars become safer and more popular. This allows the revenues from the assembly lines to be returned to ownership or investors rather than working people, the revenues from the law firm to go to the partners, etc; in other words the already-wealthy get a greater share of the pie and the working poor may find themselves the no-longer-working poor. Hoping that developing technology will solve the problem by itself is futile. And wealth inequality is a problem, because while technology may not create jobs, what it does is to replace lower-skilled and less-productive jobs (taxi driver) with higher-skilled and more-productive jobs (self-driving car programmer); arguably there are fewer of these new jobs but they exist and we need to have the people to fill them. The high degree of wealth inequality means a high percentage of the population cannot afford the sort of educational opportunities that would qualify them for the high-skill jobs; despite the genuinely horrible employment conditions many high-tech companies (mine included) are desperate for highly qualified employees!
I already said this? There is a difference between developing technology, and technology shocks. Slow technology development generally helps the owners of capital. Technology shocks hurt them. Think of the aristocrats during industrialisation. They were the old owners of capital (the land) but industrialisation made the land virtually worthless, suddenly more wealth could be created on very small plots through industrialisation. Factories were the new capital, the holders of the old capital mostly lost out. This is the story of the world, you get long periods of slowly increasing inequality, followed by a sea change in the economy, which destroys the old capital, and leads to a sharp fall in inequality. This is why falling gini coefficients are linked to strong economic growth, its just that its the strong growth which lowers the gini, not the other way around.
I generally agree that more education would be better, but my experience at university is that very few students actually benefit from being at university. Its mostly just signalling.
I think that wealth inequality is something we have to live with. I don't see any genuinely reasonable solutions. I think wealth inequality will continue to rise for as long as interest rates continue to fall.
For example, it is self evidently true that that a wealth tax will lower wealth inequality, but in most plausible models it does so by liquidating assets and turning it into consumption. However, by liquidating investments you must be reducing overall production, and you cannot buy more than the total production, so the increased spending just leads to inflation.
Of course, this might not be true, there might instead be foreign buyers happy to come in, and so investment is not lowered in the US, it is just lowered in other countries instead, which is not an ideal situation. Now you might argue, perhaps correctly, that moving this money means the economy changes to produce more of the stuff that poor people want, and fewer luxuries for the uber rich, but I don't really believe this will happen.
Striving for inequality of consumption is clearly a better goal than wealth inequality. To a large extent it is even achievable:
Focusing on wealth inequality is the wrong goal imo.
