Raising minimum wage is basicaly an excercise in futility. You could raise the minimum wage to 12 dollars an hour and all that would bring along with it is cost of living increases. The cost of rent would go up right along with it, and the places that pay minimum wage would have to increase the cost of all the goods that they sell right along with it. Either that or they would have to hire less people, or else hire people under the table who are willing to work for less then minimum wage, so it would just serve to kill jobs.
I worked reffing hockey games from the time i was 12 years old, (which paid less then minimum wage) and then i served my time as a McMonkey flipping burgers when i was 16, quite frankly it serves as a good motivator that you dont want to do those jobs for a living. No one goes in to a minimum wage job thinking that is where they want to be for life, its only supposed to serve as a stepping stone, or else get you in the door at a place so that the people who work hard can work their way up.
Plus a large portion of the places who pay minimum wage are places where the person working can also make tips. Take a waitress for example, my buddy who owns some bars said that some of his better looking servers who are good at flirting with the drunks can clear 60k a year, and thats almost all cash money so when you factor out taxes thats like 70k+/year when compared to a taxable income. Raising minimum wage would guarantee that he would either have to charge more for drinks(which would directly cut into their tips), or hire less people, or else go out of business altogether, whereby no one would have a job.
Basically raising minimum wage is nothing more than a circle jerk, the people who actually work at whatever the preset minimum is are always going to be poor, whether the wage is 10$ per hour or 20$ per hour, because of all the unintended consequences that come along with the wage increases. The government is never going to legislate poor people out of poverty, all you have to do is look at what a colossal failure the so called "war on poverty" has been to prove that.
