You start by stating that $15/hour is not enough then you follow-up saying we should set minimum wage at $15/hour.

How would that help?

Are you simply HOPING that raising minimum wage to $15/hour will result in an increase in wages for college educated technical work beyond $15/hour without also resulting in inflation?  Why should a company hiring for that technical work pay more than $15/hour just because minimum wage has changed?  And if an increase in minimum wage drives up ALL wages, how can that possibly not result in inflation of all prices, rendering the increase meaningless?
