If corporations paid the same tax rate as they did under Ronald Reagan, governments in the U.S. would have enough money to fund prekindergarten for every 4-year-old in America and higher education for every American attending public colleges and universities, according to a Huffington Post review of government data.

Corporations paid an effective tax rate of 31.7 percent on average during Reagan’s eight years in the White House, according to Commerce Department figures that measure corporate profits and taxes paid to local, state, federal and foreign governments.

But in the seven full years President Barack Obama has occupied the post, corporations have enjoyed a 22.8 percent effective tax rate on their profits, Commerce Department data show.

The average annual difference, if applying Reagan-era tax rates to Obama-era profits, comes out to $166.7 billion.
