Income taxes are also the exception to the rule theoretically.

Because people have a time constraint, there's an inherent tradeoff between labor time and leisure time. 

Taxes reduce people's budgets, which usually reduces consumption of goods. So, if leisure is a normal good, then income taxes will actually increase hours worked.

No, income taxes are for parasitic revenue. Really don't think anyone goes, "mmm, yes let's tax income so people earn less/work less"

Perhaps we can use this to understand who the states sees as an ideal citizen. As the Lord Jesus said, who among you is without tax?
