With Tax Day upon us, American families and employers are keenly aware of the deep cut the government is taking out of their household incomes and hard-earned profits — especially during the slowest economic recovery since the Great Depression.A heavy tax burden means consumers have less of their income to spend in the economy and businesses have less for hiring, expansion and investment. So when taxes go up, the rate of economic growth goes down.Even though economic growth is what we badly need to hasten our recovery, many of our leaders in Washington are hungry for even more tax revenue. Some still champion a big government agenda that requires greater resources to implement more programs.To pay for it, Senate Democrats recently passed a budget with an additional $1.5 trillion in tax hikes.
