However, taxes and welfare already address the issue of hungry people (I don't particularly care how angry a person is). My problem is not with the goal of redistributing wealth, but with the minimum wage as a way to do this. Since the tax authorities already know the figure that we are really interested in (how much money a person makes in total), it makes more sense to lower the tax rate on low income earners, or increase welfare, than to increase the minimum wage.
I still don't understand the logic of "X will make people angry so you shouldn't do X". Since I already care about how well off poor people are, why should I care about what makes people angry directly. While the government needs votes to stay in power, that doesn't change what in theory is the best policy, it just restricts the set of policies that we can choose from. While increasing welfare and decreasing tax on the poor, while (possibly) removing the minimum wage, might make some people angry, I don't see why this makes it a bad policy.
