I look at the situation as, "If someone can work full time and 'barely make enough to feed' themselves then that system is bad". It might not be 100% bad but it certainly doesn't fit into the good category.

Should we legislate for a better economy even if we are taking money away from the rich? Well in some senses the rich are existing as part of the economy and part of our society. So if they choose to use our money then we can choose to take some of it back as tax.
