Kaos - I get your point, but one of the arguments by those in favor of raising the minimum wage is that inflation has risen faster than the minimum wage. So while yes, you could survive back then making $3.35/hour, people nowadays are struggling because $7/hour and even $10/hour are failing to keep up with $4/gallon gas, $4/gallon milk, $15k+ for a reliable car, $10.50 movie tickets etc.
The problem I have with all of this is that inflation has been caused by the government and the government has not acknowledged their responsibility for it and instead is trying to do things that make it seem like it's the citizens' fault, which only the government can fix.
