instead having a large government or a small government, what about a medium sized government?

A fine idea, but what is the medium? If you put Shaq into a size medium shirt, it would either rip to shreds or kill him. Put that same shirt on Kristen Chenowith and you won't find her for days.

Also, tbh=to be honest.

I think efficiency, openness, and honesty are more important than size

The problem is, we are always promised these things in the run-up to elections, and we never get them. So we end up getting behind the rhetoric we like, and the only thing that changes is that government encroachment expands no matter who's in office.

Personally, I'd prefer things like defense and healthcare in government hands as opposed to corporate ones. I don't believe either should be looked at as an opportunity for profit

The vast majority of life-saving drugs and advanced weaponry were developed here because of the profit motive. Talented people, the people who develop these things, deserve to be compensated for their talents because there is a big demand for these things. What happens when we reduce/remove the incentive to develop the next wonder drug? The next smart bomb? They'll take their talents to someone who will pay the going rate for their labors. Maybe - hopefully - that someone will be friendly to the United States. I'd rather see us continue to produce these things and sell them to the world rather than buy them.

The reality is that we are all motivated by profit. I think a better economic system is one which integrates that dynamic rather than rejects it. The Soviet Union didn't exactly dazzle the world with its exports back when it was one of the world's two biggest superpowers.
