I think he is perfectly right for the very reasons he wrote. The lack of direct investment of an (greatly) increased share of the national income is no good for the aggregate demand. It is 'just' one part of a bad economic spiral but still not a good one for the whole economy.
BTW dividends would of course tend to go to people which will reinvest most of the captial, buying assets instead of consuming. At least Uncle Sam would get more revenue and this by hardly taxing the poor.
