The economy hasn't made sense at all over the past 10 years. Companies have been hiring people just for show. Startups are all about putting up smoke and mirrors to appeal to a bunch of dumb investors.
Snap never made a profit in almost a decade yet its market cap is $17 billion. Uber hasn't made a profit in over a decade, market cap is $50 billion.
If you want to understand why things are like this, just look at how the Federal Reserve Bank of the United States is constantly injecting new fiat money into the economy and you will have all the answers.
