Again Occam's razor. Your are applying to much to it.
There's been no push to overhaul H1B as it has little political value for the politicians. I see what people are frustrated about especially those on H1B but I don't think it is some cynical reason by the politicians - its more that it has little to gain for them.
It's a non-voting group of people and it isn't a large enough issue for any of their voting base.
It is not some weird theory about keeping H1B an underclass and putting downwards pressure on domestic employees.
But it will cause them a loss from the big donors that do benefit from H1-B people having less negotiating power, which is why the cynicism is warranted.
“Occam’s razor” is for situations where something is happening unintentionally. There exists intention here, however indirect.
Occam's razor: "It is generally understood in the sense that with competing theories or explanations, the simpler one, for example a model with fewer parameters, is to be preferred."
