2. Capital tax is tax on your company's money.
3. Income tax is tax on your money.
With either tax, the economic system that consists of you and your employer is being robbed.
Speaking of which, if someone takes your groceries and runs, just before you have paid for them, that is shoplifting. If it's just after you paid, it's robbery. You might think you're better off with the former, but shoplifting raises prices; some of it is shifted onto you, so that it is effectively robbery.
2. It doesn't follow that when companies have more money their workers get more. Evidence is: record profits concomitant with layoffs, corporate profits vs wages, etc etc.
3. Taxes fund a government that answers to me. Capital powers corporations that not only don't answer to me but likely want to exploit me.
That's why taxes are instigated where they are.
I like that stuff, and I'm pretty confident corporations wouldn't have done it themselves without a democratic government forcing them to.
There's a meaningful difference between democratic governments and corporations, and governments don't have to be perfect for this to be true.
Except differences in tax rates will have significant impact on what type of income people want to earn. If personal income is taxed lower than capital, then people will want to increase their income through work.
If personal income is taxed higher than capital, people are incentivized to build more machines than the economy needs and this will put people out of work.
