I am against raising mininum wages for 15 dollars an hour?

Do you know why I am against raising the minimum wages for 15 dollars an hour? First it is going to hurt all small business running the store. The first thing employers will do to cut down all employee hours or lay off people when the minimum wages go up. Second thing, they have to raise the price to keep up the store to survive. Most company have no choice to cut down benefits to all their employees. We are mostly like to see robot by replace human jobs because robot doesn't complain, never late at work.

What do you think about raising minimum wages for all their employee? I want to hear your opinion?
