"to survive on" Gee, is that the new American Dream?
For someone making minimum wage, yes.
Do they have a right to more than they need to survive without working for it?
"The Right...if not working for it"? First, those who earn minimum wage are in fact working; next, those who earn only minimum wage may not be able to thrive and better their situation unless they rely on government aid.
Most minimum wage jobs require working on ones' feet. Expecting someone to improve their lot in life while working a minimum wage job by attending a Jr. College, or one of the many for profits, is next to impossible given the cost, the time required and likely transportation costs.
Callous conservatives (CC's) oppose welfare and government aid in all forms as well as raising the minimum wage. Many CC regulars on this forum refer to government aid as stealing from them and taking the food off their families table.
I suppose CC's have always existed, but in the recent past they were depicted as snidely whiplash, Nell as a lazy no good leach and Dudley Do-Right as a government agent paid too much who wants to redistribute the wealth. That the ethos in America changed is obvious, and I suspect it all began when the Messiah told the masses, "it's your money", transforming greed from a deadly sin into a virtue.
