Robert Reich thinks we should tax income over $500,000 at 50 percent. Who am I to say to no? Considering the magnitude of challenges ahead for America, it seems only reasonable that taxes should rise on the wealthy. Taxing the super-rich is not about class envy, as conservatives charge. It's about the nation having enough money to pay for national defense and homeland security, good schools and a crumbling infrastructure, the upcoming costs of boomers' Social Security (the current surplus has masked the true extent of the current budget deficit, but it won't for much longer) and, hopefully, affordable national health insurance. Not to mention the trillion dollars or so it will take to fix the Alternative Minimum Tax, which is now starting to hit the middle class.
