Correlation doesn't prove causation, but make of the following charts what you will. Our first chart shows how much U.S. businesses have paid in both payroll employment taxes and the corporate income tax as a percentage share of GDP in each year from 1960 through 2012 (now corrected to show through 2012 - the original version through 2010 is here):
This chart shows that the total amount of taxes paid by businesses to the U.S. federal government has remained fairly steady as a percentage share of GDP from 1960 through 2012, but the composition of the taxes they pay has changed over time. Before 1978, U.S. businesses paid more in corporate income taxes than in payroll taxes, but since 1978, they have consistently paid considerably more in the form of payroll taxes.
The reason why that changed after 1978 was a series of increases in the employer's portion of Social Security payroll taxes, which were offset by reductions in corporate income taxes. During that time, employers went from having their payrolls taxed at a rate of less than 5% before 1978 to be increased in steps every several years to reach a much higher rate of 6.2% beginning in 1990, where it has held level since. Social Security's tax rates were increased during these years to ensure that the program would remain solvent.
What kind of effect do you think those tax hikes would have had on U.S. businesses, where suddenly, it became a much larger penalty to have lots of people on their payrolls in the United States? And what about those businesses where it really doesn't matter that the jobs be done inside the U.S., like manufacturing?
