Every healthcare system the US government operates operates at a loss. That's all I'm saying. The US government doesn't turn a profit on anything it operates. In fact, every system the feds operate that I'm familiar with operate at a loss. Medicare/medicaid all lose money. Social Security loses money. And if you try to deal with these systems on a regular basis you quickly find that they are anything in the world but efficient.
Set all of that aside for a second. The fact is that culturally people here do not trust the government at all. The last thing they want is government in charge of their healthcare. As I mentioned earlier, the government runs the VA healthcare system from the top to the bottom. They have full control over everything. Your dog gets better care. Just saying.
