If a poor family only has $500 to their name and has to spend $100 to buy water just to survive, they've blown 20% of their total networth just to survive. A middle-class family spending $100 of 15,000 is far more likely to not be affected.
It's hard for me to understand how many people on HN can't fathom that price gouging affects the people most hurt by disasters. I don't care if price gouging means you'd gather up more supplies and head to a disaster zone because you're still taking drastic advantage of the poor for personal profit. Countries like Japan don't pull this same shit, so it's too bad that we rationalize our greed as being 'for the greater good'.
We all have a moral duty to use our franchise as citizens to keep these points of view out of government.
If we allow the price of water to rise when supply is constrained, people who can afford the higher prices will use water more conservatively and board less, and people will still give it away to those who can’t afford to buy it. But people won’t have to wait in line all day to get their ration of water, and there will be incentives to create temporary channels to improve the supply of water even if those channels couldn’t be supported by the normal price of water.
And you say you're making fewer people suffer; I say you're disproportionately forcing the poor to take the brunt of the suffering.
In the other system, water is apportioned according to who can get to the store faster, and supply never goes up because nobody has a reason to restore it. People use drinking water for washing if they have it, because it's not like you can sell it anyway.
In both scenarios the is significant inequity (whether by money or ability to get to a store fast and fight/negotiate for water). But overall, many more people suffer in scenario 2. This is obvious given all the suboptimal water use in scenario 2.
It's hard for me to understand why you'd prefer a scenario where obviously more people suffer.
