Because I can't compete with those people and have a life worth living. I'd prefer suicide.
How do you think those people feel? Where are they coming from that $10/hr seems like a good wage?
At least you're honest. The truth of minimum wage laws is that they are intended to squelch competition in the labor market. They've long been promoted by unions and labor advocates to target 'scabs' - people who are willing to work for less than the union is demanding.
But at the end of the day, the sad fact is you can't increase the value of your labor by decree. You can't force an employer to pay a given amount. They can always choose to not pay you anything at all, to get by on fewer employees and simply lay people off to cover the increased labor rates. Which comes back to your 'screw the other guy' point of view. Minimum wage laws are actually about banning low wage laborers, or rather, making them illegal. They will still work regardless.
