After the housing crash, you'd think we would learn our lesson of what happens when policy is born from sweeping generalizations based in envy. Everyone deserved the American dream of home ownership, so we enacted laws that lead to housing prices skyrocketing and subsequently crashing when people could no longer afford to live. But here we are, as always, bitching and moaning about how to make things more fair and give everyone what they deserve.
I too would like to see policy that equalizes incomes, but it has nothing to do with envy. It's more about economic freedom and welcoming people into the upper middle class. As it stands there is little incentive to work too far up the chain.
There are labor issues on top of the tax problems you two are examples of. I could become much more productive but my industry has this nasty way of tying people into a job for a few years and then working them 70 hours a week on 40 hour week wages. Between the hours and taxes the trade off isn't worth it. "Exempt" is a dirty word from my birds eye view.
The incentives aren't there because our government has failed to protect them. Hard line conservatives effectively stop any labor gains regardless of the underlying situation. After all, nobody forced you to sign the contract. I guess conservative principles don't account for indentured servitude, usury, or any other practical slavery. Hard line dems are polar opposites, so we end up with a fight rather than a solution. We "unprincipled moderates" get hurt over the ideals of 50,000,000 American extremists. Fun, fun.
