All of which are still massive companies, with Walmart pulling in half a trillion per year in revenue, double that of Apple or Amazon. Stock market value only tells part of the story (that of the richest getting richer).

Walmart has a well-understood business model, and so there is less uncertainly/risk, which means that investors generally accept lower returns for greater certainty.

The impact and revenues of tech companies is more uncertain, which is more risky, so investors are asking for more return in exchange for taking on that risk.

Some of the past recent he's found has shown that investing in a company on the way to being a Top 10 gets you good returns, but once a company is in the Top 10 its returns actually lag the market average.

As for income/wealth disparity: redistribution was used to good effect post-WW2 with high marginal tax rates, and it's also why the idea of a 'baby bond' is gaining some traction.
