The problem is that just a wage increase will not fix the underlying issues. And while it may fix the issue in the short run, everything will just end up back where it is now. The only difference will be that #'s will change on people's paychecks.
Say I'm a dirt bag property owner and you rent from me. Well now that minimum wage has gone from $8/hr to $16/hr that means you theoretically have double the money you had before. Guess what? I am going to raise the rent now, because I know that the majority of my renters have more disposable income.
Now say many places did that? Now we are back to square one.
