The running up a huge deficit is a strange one by any logic. I guess it's on the principle that if I owe $100 it's my problem, but if I owe $100 trillion it's your problem. Whatever, it's never going to be repaid, EVER.
In the US there isn't any difference between parties or politicians- all out of the same box. Any difference is only window dressing to pretend the voters have a choice.
The US is a strange one- proclaims itself to be capitalist, but isn't, the people are frightened by the word "socialism" but want social security and medicaid.
I liked NZ in the 70s, actual socialised public health, the state owned the railways, and the power system, the telephone system, then they went and privatised everything and it's been a disaster.
