Looks like some of the states have gone quite a bit above the federal rate. I'm especially surprised by Missouri: ...
There are no states with minimum wages
between $7.26 and $9.19/hr. If states are the lightest color, they have made concerted efforts to resist raising it. They are all at the bare minimum, and the fed needs to increase the national minimum to a more livable wage. $7.25hr is a joke, and the states with minimums of a few dollars an hour for servers are even worse.
It's predatory for unskilled job employers, taking advantage of their workers and the states enable it for the sake of "good business".
