Greed is good, it's not an insult. If someone calls you greedy because you don't share your stuff with them, it means they're just as greedy, they're just also envious.
For people still selling at unreasonably high prices, if they can find buyers then all the power to them. It's not like there's some plague and they're hoarding the only vaccine.
Gas prices at the pump go down eventually, but it's all about pressures. When you look at gas prices sometimes they are slow to move, and sometimes they drop hourly (price war). But in the big picture prices are not that simple, because of the options market. Essentially prices are influenced not just by people guessing what the future prices will be, but also by people guessing what other people will guess the prices will be. Gas isn't bought at the price you think, people buy options to buy contracts at prices they guess, and if the price goes to that level they can buy the amount the option was for. But they had to pay for that 'option', and the option has a deadline. Every day closer to that deadline the option is worth less and less money, until it lapses and then the option is worthless. So throw in people trading these options, and you have a very confusing market.
Plus gas stations aren't selling you gas at the price they paid for it - they bought their supply and sell it at the price they think they need to to raise enough money to buy the following week's supply - so they're always going to be jumping the gun on price increases. They do not make their living off of selling gas, they make their living off of shop work or potato chips.
