Since when is it the government's role to overrule individuals to decide that contracts not signed under duress are "unjust"? I don't think a Lamborghini is worth $300k. I guess I should request that the government force all sellers to charge a lower price.
If someone sold you a 300k car for 1300k you might have a slightly stronger case.
