Yes, I believe corporations will increase salaries. However, not the day after a bill is signed. I believe in the free enterprise system. I believe business will pay for labor what it must to get qualified employees. No more and No less. What you are more likely to see, however, is a reduction in the cost of goods sold. Payroll tax, along with corporate income tax, are an expense, just like cost or raw materials, or labor. Those expenses are, to the max extent possible, included in the 'cost of goods sold'. If not, then the provider of capital takes a lower return on his investment, and at some point will invest is some other commodity.
