I rarely go to Walmart, but every few years I do in the USA, and it constantly blows my mind. The quantity, price and quality of 'stuff' in there ... you can live extremely well compared to anyone in 1970 just off Walmart.
I submit that the surpluses are going to consumers, but because we don't price them (i.e. the added value to you in savings or quality doesn't go on the books), it's not part of the equation.
At least in most material ways, the Western World's 'cup runneth over with stuff' ... a lot of which we do not need and is therefore luxury.
The financial profits stack up in the top 10%.
It's unsustainable, but it's not all bad news.
The other 'Elephant in the Room' nobody will talk about are the surpluses to middle class yielded form undocumented workers. The US has 10-20M people 'off the books' working for crap wages, no health insurance. That is a huge part of why everything is so cheap in America. Particularly food and restaurants (the whole value chain is migrant workers it seems).
The #1 thing America could do to reduce inequality would be to force companies to pay a real minimum wage. 1/2 the undocumented workers would be out of a job, the others would see pay increases.
All jobs have to come with healthcare, or at least pay enough such that the income can cover a basic healthcare.gov package or else - what's the point? Collect taxes and redistribute via medicare?
Taxation at the high end could be increased somewhat.
Pushing some of those surpluses into the hands of working people would be a massive boon for the economy.
