I've seen it happen overseas consistently. Unscrupulous hiring teams hired by a U.S. hired contractor goes into a country like India to recruit workers and promise them the world only to charge fees and lackluster jobs. And, this is to support U.S. contract work in the host county
There is a lot of slaving going on with unskilled immigrant labor in the agricultural, construction, extraction and hospitality sectors that has always gone on. Workers are housed in substandard housing, never able to retain enough of their wages to move out into something better.
