H1B visas are for workers in the tech sector, but they have other visas for other purposes. H2A visas are for temporary/seasonal agricultural workers, H2B visas for temporary workers in non agricultural fields. So they could be shipped in via H2B visas, or they could lobby for some new kind of temporary worker visa. In Canada we've already seen similar - McDonalds (and other similar businesses) offers non-living wages for work, and when they can't find workers for low wages, the canadian government lets them ship in temporary foreign workers to run their fast food restaurants because 'there's no workers at the market (non livable) wage'. With programs like these the free market for labour dies. Why are wages low? because companies can offer extremely low wages and when no one bites, ship in temporary workers.
