The minimum wage really only applies to the lowest-requirement, manual-labor jobs. Ideally, the baseline he’s suggesting would adjust for certain expertise fields, perhaps just around the subject of when they can request immigration visas or outsourcing assistance.
So for instance you need a software engineer, you shouldn’t be able to offer a 70k salary, get no one (because software engineers value their time), and then claim there are no software engineers - you would have to be offering 110k+ before any assistance.
