Its not clear to me what problem they're trying to solve. If its controlling immigration, higher wages won't dissuade large IT services companies from sponsoring visas because the alternative - i.e. hiring US grads - is likely to be much costlier/harder to scale and require evolving recruiting and culture practices. Far more likely, they absorb the cost or just contribute to service cost inflation.

The problem being solved is how to easily do grafts and kickbacks.
