Because if everyone involved is quitting their jobs, they’ll have no money with which to buy food. Which means they’ll have to farm it themselves. And farming, even with top-of-the-line modern tech, is backbreaking fucking work. Also unpredictable as hell: bad harvests aren’t uncommon, especially for novice farmers with no formal training like these guys would be.
In other words, one bad harvest, and everyone in the system you’re proposing fucking dies. Yeah, there’s a reason in the 1800s people were abandoning their family farms for the horrorshow of Victorian era-factories en masse: because even that hell was still preferable to farming.
Yeah, there’s precisely zero chance this doesn’t blow the fuck up in El Salvador’s face in the long run. Not to mention it’s horrific on every possible level.
Hope to god El Salvador manages to figure out a way to get rid of this guy, and fast. Otherwise they’re in for a very bad few decades.
