Because we are all shareholders and this has worked much better for us than all the shit other people have tried elsewhere.
The society whose foundations 'this' is built upon, the one that built the middle class, was built on very different rules. Marginal tax rates over 90%, strong(er) labor protections, and CEO-to-worker pay ratios today's CEOs would balk at.
'Income inequality' is really just a pyramid scheme with branding pretending it's still an extension of post-WW2 America that built the middle class. The American public isn't buying it anymore.
No we aren't? Not even everyone on this forum is a shareholder, nevermind everyone in society?
