I they spend it irresponsibly then that's up to them. The aim should be that no-one has to live without food or shelter,etc from something other than their own choice. If everyone is getting the same money then there's less need to police people on spending it irresponsibly, because it's not taking money from tax payers and giving it to non tax payers to waste. The tax payers are also getting it.
