I don’t agree at all. Who says wealthy people invest their money in ways to increase economic productivity? They blow it on consumer goods too, just far more of them. Why is a $10 million dollar home a good investment if $1000 in smokes and booze is wasteful?
Secondly, the concept that investments that improve productivity is only going to happen when that results in more profits. As long as labor is cheap and abundant, you don’t need higher productivity.
In fact, that is one of the benefits of high wages for labor. High wages for laborers increase the incentives to invest in automation and robotics to increase productivity. As long as there are endless millions of people willing to work w/o safety regulations for $5/day, there is no incentive to invest hundreds of millions into robotics and automation.
So if anything giving more money and power to laborers is the way to increase productivity. A strong union movement will do more to achieve what Sam Stone wants (increased productivity) than supply side tax cuts, because a strong and wealthy labor movement will make mechanical alternatives to labor more appealing.
Plus supposedly 60% of the time a fortune is wasted by the time kids get through with it. It is gone 90% of the time by the time the grandkids get through with it. So the rich are not experts with money when the money is handed to them via family connections.
Plus we saw horrible job growth under Bush despite the income of the top 1% and corporate profits skyrocketing. Where were these great jobs or improved standards of living from 2000-2008? I didn’t get any. The top 1% saw their incomes double and corporate profits tripled under Bush. Where were the amazing jobs, increased standards of living, etc?
And corporations are currently sitting on about 1.9 trillion in cash reserves. Are they using it to create jobs or boost productivity? Nope. Supposedly they will use it for mergers and dividends, which will cost jobs.
In February corporations had 1.18 trillion in cash reserves. By July it was 1.8 trillion.

Has it been invested to increase standards of living or create jobs? Nope.
Supply side tax cuts also means less revenue for infrastructure, which will lower productivity. A less educated workforce with worse transportation, more expensive energy, poor communications, etc. is not going to compete as well with a better educated nation with good infrastructure. So if you give the wealthy $400 billion in tax cuts, that is $400 billion that could go to investments in energy R&D, building high speed rail, funding for college, etc.
