They’re inextricably linked. The ceiling is being raised by people at the top pillaging from people at the bottom. Sure, in a vacuum, raising the floor without regard for the ceiling might work but in the real world it does not. Capitalists choose to believe that the floor today is better than the floor 20 years ago because even poor people have iPhones but when you look at the actual life people lead, it is getting worse.

If anything, “raising the floor” is the Trojan horse.

Your perspective though depends on thinking the economy/money/whatever is a zero sum game, and if a person's wealth goes up, they must have taken it from somewhere else. In general, wealth is generated by growing the economy.

This isn't to say I don't think some companies/individuals/shareholders have absolutely taken the piss compared to wage earners.
