The government doesn’t just exist in a vacuum as you seem to think. It represents the interests of those who hold power in a particular society. In the US, it is the capital owning class, and these are the people who decide to cut your healthcare, to gouge you for education, and so on. The government simply exercises their will. Entire books have been written on the subject, yet here you are confidently attempting to debate a topic you clearly haven’t spent even a few minutes thinking about.

Also, if a large central government was the problem, then we’d see the same kind of shit happening in China that’s happening under capitalist regimes.
