Should the Minimum Wage increase to $11 an hour instead of $15? Why?

I think you mean increase to $15 instead of $11.

In one recent poll, 67 percent of small business owners support the minimum wage increase to $15 an hour. They say it would spark consumer demand, which would enable them to retain or hire new employees. And raising the wage doesn't seem to compel employers to cut jobs.

It would help 900,000 people out of poverty. Raise income for 17 million people (one in 10 workers), to the tune of $509 billion over 10 years. Potentially increase wages for another 10 million people.
