See this also demonstrates the liberal/collectivist mentality that everything is a static entity. The economy is a fixed figure to them, so going from $7.25 an hour to $15 an hour in their minds means they've just more than doubled their purchasing power. In reality of course, it merely shifts everything else in the economy up by a more or less equivalent magnitude so that doubled wage is immediately met by a doubled rent, a doubled bus fare, what have you. I mean, who is going to pay $10 for a hamburger at McDonald's?
The only thing these minimum wage demands accomplish is pricing out people at the very bottom rung of the career ladder, and that's precisely the people who these types of jobs are meant for anyway. Sorry, but jockeying a register at McDonald's isn't supposed to be a job for someone in their peak earning years. It's for young people, or senior citizens looking to bring in some extra cash. If you're 30 years old and working a minimum wage fast food job as your day job, don't blame "society" for it.
