There is absolutely nothing more fair than the free job market. One party has something they want done, the other party wants compensation, and the two either come to a mutually acceptable agreement or walk away. Likely neither party gets what they would like to have, but both get what they agree is acceptable.
And "the marginal utility of money" is merely yet another way of saying "I can spend money better than the person who earns it."
Yada, yada, yada. Standard duh-versionary propaganda.
Enormous incomes are not earned through working, but rather investing. That investment requires wealth- earned, inherited or leveraged. Not everybody has that, nor can we all obtain it simultaneously. Your pablum doesn't apply.
A great deal of income is earned by dint of ownership rather than work. People who are extremely wealthy don't necessarily manage their empires personally, at all. They hire people to do it. Their sole claim to that income is ownership of the means to produce it.
Middle class conceptualizations of work & reward simply do not apply.
A lot of factors beyond our control influence our paths in life & our incomes, as well. Family background. Native talent & intelligence. Opportunity. The notion that we all have equal opportunity is a joke. If we did, GWB probably would have been the town drunk somewhere in Texas.
The notion that the enormous concentration of wealth & income achieved over the last 35 years has no effect on the rest of America is equally absurd. It's a form of hoarding.
None of this is about me personally, so you'd do well not to pretend that it is. I've done well, in part because I've been lucky to have the opportunities afforded by New Deal America when I was younger man. Opportunities for younger people are much scarcer, in no small part because opportunity been concentrated along with wealth & income in this brave new world of trickle down Reaganomics.
