Half a century ago, corporations paid 45 percent to 50 percent of the income tax. Today they pay 6 or 7 percent. This is why our infrastructure is crumbling, there is no universal health care, our public education is in crisis, regulatory agencies are impotent and our poor and working class are desperate.
