There's an assumption there that more money to government = make things better but there are plenty of examples where the government makes things worse.
Some people believe that giving less = actually make things better because it will limit the bad things a government can do.
More money or less money isn't the issue. I would have no problem with way paying much more to the government if it's for services that are beneficial, and I think we're paying too much for services that are not.
When it comes to healthcare, the vast weight of the evidence supports strong government intervention in healthcare. When examples of profit driven healthcare exist, the vast weight of the evidence would lead you to conclude that it is less efficient and more expensive, delivering worse outcomes for higher cost.
