"Since most full-time jobs involve a single employer — it’s a one single point of failure — meaning, you just need your employer to fire you to lose your income.

With a business, you usually have more than one customer and in the majority of cases: tens, hundreds, thousands, and even millions of customers who are your revenue source"

This claim is so overly superficial that it's not helpful. The percentage of businesses that fail is way higher than the percentage of people that get laid off in any given year, typically. And it's not like businesses haven't struggled to survive during COVID-- just as much as any employee has lost their job. Losing 20% of your customers can be the difference between the company surviving or not, it's not like that just means you lose 20% of your profit.
