Let's get rich!
The side hustle has been around ever since the Devil took some time off from pitchforking to sell some produce in Eden, but one of the things that I think people my generation and older don't fully appreciate is just how embedded it is in Today's Youth. Online marketplaces are way, way more granular these days than "do fifty searches on Amazon to find an XXXL crop top that says 'COOL BEANS' on the back." Said crop top has already been made by any number of individual sellers on any number of boutique sites, resold as vintage by individual sellers on any number of thrift store sites, and you're simply just not cool enough to find it.
