I don’t see why Social Security can’t be cut.
Despite the fact that, as you point out, it’s probably suicide to even suggest that we actually do that, it’s going to go away completely one of these fine days, anyway, when the rest of the house of cards comes tumbling down. It would only make sense to make real attempts to cut our debt load. After all, it’s not as if anyone is admitting that Social Security is a huge scam, anyway. We don’t have to face that reality, apparently.
Really, the fact that people are concerned about a Chinese military buildup that might make them the equal of, oh, maybe Israel or Pakistan + India… why do we worry about that? They’ll defeat us with our own debt, and get nice waterfront property while they do it, without a shot being fired. And they certainly have the patience to do it. All they have to do is wait, and continue to buy the debt we issue on what amounts to our daily expenditures. (We don’t even go into debt for ‘big things’ any more; we add to our debt for every little thing.)
While we dig our graves with our spoons and argue about political posturing on “both sides of the aisle” (as if it matters which side says what), they’re happy to buy the debt and actually grow an economy.
