Since H1B is supposed to bring in rare foreign talents to do the jobs not enough Americans are available to do, salary should reflect that. If only the highest paid people receive the visa, then the public would not complain as much about replacing American workers for wage reason.
(Even startups with limited budget often can afford $80,000 these outsourcing firms pay their top 25th percentile H1B employees. [1] For a technical co-founder role in a Bay area VC-backed startup, it should be higher still.)
Why has this obvious modification not been implemented? I suppose it does not need Congressional approval. Is it because the change would be against certain major corporate interests?

Response to objections:
Objections below regarding salary differences between fields (scientists vs bankers) and costs of living in different areas can be addressed by considering average salary in each field and area. For example, how much higher, in percentage terms, the minimum salary of the proposed H1B is, compared to the average of comparable positions in the same area. (Details need to be worked out, but the same is true for other important systems.)
Assistance to startups can be given using a point system (like Canadian visa) that grants extra points to applications from smaller companies. This extra benefit would also help level the playing field in terms of overhead costs which is a much larger burden for these companies.
