Your example is a perfect example for unintended consequences of each and every government's decision.
I can give one more example. There may be some bona-fide less desirable locations with low wages, that do have difficulty attracting qualified personel. This will be a burden for some organization in the midland of America trying to hire a skilled worker.
That being said, every law will have consequences, the outcomes that the politicians would not want to think about it. Here are the few: the limit of $100K does not appear to be indexed to inflation. Which means that in a decade the new limit of $100K will become what is now $50K.
As others already mentioned, some jobs a highly telecommutable. IT, accounting, calling centers are frequent examples, but there are many more. Because of never ending increases in taxes (local property taxes), workers demand 2-3% annual raise, annually compounding corporate costs. Basically, because of the increasing taxation and now mandatory health tax increase (wait for 2017 enrollment period), more companies will be looking for ways to cut the costs and will outsource the jobs.
Even president Trump with his promises will not be quick to help.
Finally, US will become less desirable destination to study. Which is a good thing, of course, because it will help to prick current US study cost bubble, as less foreigners (paying full price) will come to study to the USA.
All in all, increase is probably a good thing. However the blowback will be very different from what people expect.
