"But they'll take the jobs with them"
A) No they won't. It's expensive as shit to uproot your entire operation, rehire, retrain, and reorganize entire production lines from the ground up, not to mention a gigantic pain in the ass.
B) Even if they do, that will leave a hole in the economy which can be filled by small business and entrepreneurs.
C) Even if it doesn't, trickle down economics is a filthy lie sold to you to keep you complacent. You can do better than a below minimum wage gig economy sidehustle. Demand better from employers.
