It is not that McDonald's doesn't want to pay it, it is that the people don't want to invest the time, effort, etc. to acquire the skills to qualify themselves to be able to bring $20 per hour worth of value to the company. They want it because they think McDonald's owes it them just because they show up every now and then when scheduled. If you aren't happy with what you are making, develop marketable skills and take them elsewhere..
that's exactly what I meant, I had to work in mcd's when I was down on my luck
I saw it for what it was a temporary situation, I was happy to work while I looked for a better opportunity
You just don't see that attitude anymore
