You're talking about the entitlements that are leading to fiscal disaster. If they wanted to destroy these programs, the best way to do it is to do nothing and watch them implode on their own in the coming decades. To save them means to either cut them or increases taxes significantly across the board. Just raising taxes on the rich won't even come close to covering the promises made.
The Republicans in the House have actually passed a budget. The Democrats in the Senate have failed to even present a budget in over two years.
As for destroying the country, if not raising the debt ceiling on August 3 will lead to catastrophe as the administration has argued, why won't the president agree to a short-term extension as Republicans have suggested? After all, it's a bit ambitious to expect to come to an agreement on such huge issues in a matter of weeks.
And the tax increases would be for couples making over $250,000 and individuals making over $200,000. And it would effect you if those people didn't hire you because they had to pay more in taxes. Such a cost is invisible but just as real. Besides, the money that can be raised by increasing taxes on wealthy individuals is so miniscule compared to the magnitude of the problem that anyone who proposes that as a chief component of their solution simply isn't serious.
