ELI5: Why don't US veterans have fantastic health insurance/healthcare?

A lot of posts talk about how terrible the VA are at taking care of veterans, especially relating to medical and psychological care. For a country with such a well funded military I would have thought the funding for this would be a slam dunk. Who gives a shit if somebody pays for your coffee. Why can't they show up at a hospital and receive treatment payed for by the federal government? Shouldn't that be the least they could do?

These things don't come free - somebody needs to pay for it.  You can't just pull money out of thin air and magically give veterans healthcare.  For the last few decades, suggesting tax increases is pretty much political suicide for any legislator who brings it up.

Part of the reason that we have VA hospitals to treat veterans is that it's cheaper to provide services when you don't have to worry about all the overhead of for-profit insurance companies, doctors & hospitals.  Ideally, we'd reach a point where we have a single-payer system for everyone & most of this problem would go away but there's a **lot** of resistance.
