You could easily add a clause that says if you have a useful 4 year degree from the US, the minimum is $75k (or whatever) and 100k for everyone else. Then new grads wouldn't be at an unfair disadvantage for getting jobs.
Keep in mind, also, that few of the ideas on this thread haven't already been implemented by some country (Canada, Australia, etc.). It would behoove politicians to look at the resulting data instead of voting on measures that affect groups they don't care to understand.
