Set the thresholds using a countrywide baseline (1.0 = countrywide median household income) and adjust according to the median household income of the city the job would be located in. Also adjust thresholds based on the profession.
Those same companies then claim position is small town x, but that office magically closes when H1-B arrives.
A better way might be weighing based on the applying company. Give a weight based on the size of the company and another for the type of company. These weights would be assigned based on the top-most owner(s) and not the applying companies themselves.
Also add penalties for larger companies acquiring smaller companies with H1-Bs that were hired within the last X number of years. Not sure what penalties exactly. At least financial to fund the system, but probably to the weighing as well.
