So if the dot com bubble had just continued we would have had no national debt by 2010? I mean hey, why not right?
No. Paying off the debt didn't have anything to do with the dotcom bubble. Even with the bubble bursting in 2000, we had a record surplus that year. 2001 also had a surplus, but it was lower because some of the Bush Tax Cuts started in 2001.
If Conservatives had done literally nothing to the tax code, we could have paid off our debt by 2010. But Conservatives can't even do nothing right, so the debt was doubled by 2009 instead.
