It's been noted that government control of industries tends to increase shortages, rather than decrease them.
Ok, then for whatever reason, there is a shortage. Now what?
Well, temporarily you can ration essential things in that local area so nobody dies.
But you get out of it in the long run by letting prices rise, then competition fills in the gap, and prices come back down.
It's debatable whether the former is even necessary except in extreme cases, and maybe not even then. In the US, hurricanes hit the southern coast. Power is out. People want to buy ice to keep food cool.
Ice bag prices skyrocket.
People in the north load up trucks of ice bags and drive south and sell them for $10 or $20 per bag.
Politicians pontificate, how horrible! How awful to take advantage of these people! This is now outlawed!
Take a guess what happens. Take a guess at what the average ice-ownership and food-spoilage and food-hunger rates of the affected people become.
Hint: Nobody's gonna fill a truck with ice and drive it down there to sell it for what they paid for it.
Oh, and there's more to this. For Katrina, government tried to make up the difference. Eight hundred quintillion tons of ice sat in ice warehouses over fifty thousand miles away for two years, then was destroyed as not fit for human consumption.
As another anecdote, a company near me just spent $15 million to recover and refurbish a derailed train engine worth $2 million, when scrapping it on site would have cost $1 million. The reason? They didn't have money in the budget for purchasing new engines.
My anecdote beats your anecdote I win.
Oh, here's another anecdote for you. The privately run American healthcare costs more than any other system in the world, and delivers worse health care than quite a few.
Oh wait, that's not an anecdote, that's a fact.
