Subsidies seriously distort the market.
IMO the only kind of subsidy should he “If you’re a human, you get some money on a regular basis”. That’s the only way to subsidize economic activity without distorting market signals, because humanity’s choices is exactly the signal source that the market should be responding to.
That’s basically how medicine is run these days, and that’s a result of the artificial supply restriction government places on medical facilities and staff.
All doctors are forced through a narrow gauntlet which is basically designed by government regulations. The result of that process is doctors that have reduced empathy (it’s been documented, look it up), sleep deprivation, enormous debt, and a huge workload.
As a result, the third leading cause of death is medical malpractice, and people go into financial ruin to get medical care.
Medicine is one of those things we deemed “too important for a free market”, and so we’ve created a horrible hybrid of profit and government regulation that consistently produces horrible outcomes.
We need to be careful with this notion that something vitally important will be made safer, or more reliable, or less damaging by getting government involved.
If we aren’t careful (and let’s face it: government cannot be careful because it operates on a feedback loop of years, not days like private enterprise does), regulating the fuck out of a growing nuclear sector could lead to error and burnout rates similar to our medical sector, with similarly disastrous results.
