Businesses have to match the taxes that employees pay. If i make $50,000 a year and owe $10,000 in taxes, my employer also owes $10,000 too. So if my company is paying taxes on my wages, why are the CEO's wages tax deductible?
All wages (whether you're the janitor or CEO) reduce a company's profits, which means lower corporation tax. You are talking about payroll taxes, which are a different thing.
