The usual story: When Republicans want to create more public debt by giving tax cuts to rich people, they say debt doesn't matter. When Democrats want to create more public debt by investing in infrastructure and education, suddenly everybody (including some Democrats) jumps on the Republican concern trolling train about too much debt. There is a big difference between bad debt (looting the treasury for your cronies), and good debt (buying stuff we actually need that has a high ROI.)

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
