On the whole, this is a ridiculous article. No one except rich elites cares about the deficit (including the bond market: 30 year treasury notes are yielding 4.5% right now). Republicans may have made noises about it in the last election, but one of their major planks was that the Affordable Care Act cut Medicare benefits!
We are in the middle of a global economic contraction, it is not the time to be reducing spending (redirecting spending to useful infrastructure, sure).
The calls to cut Social Security are especially irritating. Thirty years ago, Reagan increased Social Security taxes to save the system. It worked, and the Social Security benefits are fully funded until 2037.
For 30 years, workers have paid extra into Social Security to keep it solvent long-term. Now a bunch of rich elites demands that benefits -- that they don't need, but millions depend upon -- be cut. That is a bait-and-switch of the highest order.
He doesn't even talk about Medicare, which is the real budget problem. You can tell if someone is serious about reducing the budget deficit if they have a real plan for Medicare.
Despite my disagreement on entitlement spending, I appreciate that he thinks military spending could be cut and tax rates on the wealthy need to be raised. Since he's wealthy, I appreciate that he is willing to make a personal sacrifice.
