> Also, Companies actually contribute more in taxes than people like to admit. They pay workers' wages..and those wages include tax money that goes to the government.

That's still a tax on the workers' wages, not a tax on the company. If we shifted all income tax into a payroll tax, then by your definition workers aren't taxed at all? Anything that increases the cost of employing a worker will reduce the marginal net benefit of employing that worker, which will result in either lower salaries, fewer employees or both.
