IIRC, prior to Smith's famous book, the wealth of nations was viewed in terms of gold kept in the coffers of the kings. This was increasingly a source of puzzlement because it was failing to explain why some nations were thriving and others were not. This seminal work has been credited with being single-handedly responsible for transforming our understanding of wealth as "gold in the king's coffer" to what we now refer to as GDP. Wealth of a nation is measured by its productivity, not the money in the bank.
While I agree we need to do something about the current trend towards concentrating money in the hands of the few, clearly at the expense of the many, this is not the way to do it. This in no way protects the productivity that gives rise to these riches. In fact, it is likely to undermine said productivity.
There is no limit to how much people can spend. If you just cut everyone a check, whether you call it Basic Income or American Equity, the money will get pissed away. It will not get invested in a better future.
We have to find ways to address the underlying structural problems that are causing the 1 percent to effectively bleed the masses for more. We also must do so without creating perverse incentives. This is a case of "the cure they are recommending is worse than the disease."
