But slave labor is essential to the existence of well off, wealthy and super wealthy people.

You can see that in ~about~ mid 20th century, when very high marginal tax rates of very high earnings reduced the incentive for owners and executives diverting profits from wages and into their own pockets, bonuses and spaceships.

Difference between a CEO's pay and his lowest or median employees wasn't times thousands. Now it is, thanks to free market slavery.

In those days, what we now euphemistically call "essential" jobs could actually support a family, a mortgage and sometimes college for the kids.

Now an essential job provides essential support to everyone except the wage slave. Me included, as I enjoy my free and same-day delivery book with my cheap WalMart oatmeal and cheese.
