It's an oldie but a goodie: several years ago, a software developer outsourced his entire job to China way back in 2013.
It worked for awhile. In fact, he was seen as the best developer in the building. And he gave the Chinese firm $50k while earning close to $200k himself.
Clearly there's a right and wrong way to go about outsourcing to freelancers. His was strategic but not collective; effective but not mutually beneficial.
