It's "What percentage of their disposable income (ie, net of housing, food, health care, and other necessary expenses) do each quintile/decile/etc pay in taxes?"
And the answer is going to be that the middle and working classes pay a huge percentage—close to 100% for many—while for the wealthy it's effectively nothing.
The important thing is funding the state, not making a personal sacrifice. The economy is based on value, not pain.
The top marginal tax rates during the right's supposed "golden age" after WWII were much, much higher than they are now.
But regardless, "if you try to make the rich actually participate in and contribute to society, don't be surprised if they try to destroy society instead" is exactly the kind of threat that supports the idea that we should, instead, make it impossible to be rich enough to carry that threat out.
Having a functioning and mutually beneficial society is much, much more important than letting outlandishly rich selfish people stay rich.
