I'd go a step further and say that (particularly if you are in the IT industry) and are also ideologically opposed to megacorps like Facebook, Amazon, etc. that you should deny them the power of your labor.
This is such a weird take. When choosing what to buy, it’s impossible to factor in whether or not you believe the seller is already too rich. How could such a market ever determine the price of goods?
No, free markets work reasonably well. What doesn’t work is extremely disproportionate wealth, which is a result of neoliberal policies from the 80s. Revert those policies (i.e., actually tax the wealthy), and get back to medium healthy economy of the 60s and 70s.
