The size of your wallet is neither a physical attribute nor a skill to be acquired.
Going from having nothing to being wealthy comes neither from hard work nor skill, though both help to a degree. It comes from luck. And once you've landed on top, by luck of the draw, you can just pay other people to pay others to pay others to work, and the results of that labor trickle back to you, while you fill some figurehead position, paying others to do your thinking for you, and otherwise live a life of opulence.
Further, at that point, you are gaining the most out of government services, both protection of your (vast) property from fire and theft, the creation of an educated workforce to employ, roads for your employees to reach work on, social welfare programs to prevent an angry, starving mob from lynching you in the streets and stealing your assets, institutions to enforce conditions of business transactions, an army to prevent other powers from seizing your assets... So why the fuck shouldn't you pay a larger percentage of your income than some poor bastard who's making minimum wage (which is, even were it untaxed, still several thousand below the amount required to maintain the minimum acceptable standard of living), who also pays outrageous sales taxes on things required to survive?
