>What do you mean by "high minimum wage"? Federal minimum wage in the United States is still $7.25 which is not enough for someone to live on, especially in a high cost of living area. I don't understand.

He/she means "higher than the federal minimum".

Homelessness problems seem to loosely correlate with cities and states that have higher minimum wage (edit: so do many other things and homelessness problems might actually be correlating with one or several of those).
