Another industry which often flies under the radar of many people is the marketplace for products which eBay, Facebook Marketplace, Amazon, PayPal, Stripe, etc. will not touch. The market for [non-FDA] diet pills, MLM eBooks, "mind, body & soul" empowerment videos, etc. is massive - even more so during the pandemic when employees are getting bored at home. A business I knew with saw revenue rocket during the last 2 years, and they owned the whole stack - affiliate marketing schemes, an ecommerce platform (which still supports IE7!), virtual call-centres, right down to a payment processor (that also accepted adult content, CBD products, etc.). The experience really opened my eyes into how much money there is to be made by... how can I put this politely.... exploiting overweight gulliable people with low self-esteem.
