Technically, someone could increase expenditures without making an effort to increase oversight, so the government wouldn't expand. The idea is horribly rittled with flaws of course, but it is an alternative. In fact, I think it's actually been the current administration's policy.
I'd just like to note that an idea of a bigger government doesn't actually bother, depending on how it is expanded. Having tons of people employed by the government could be positive, since it could fit my "be the government" philosophy. That would mainly be true so long as the government were run more like a cooperative than a corporation.
