For small businesses, they often can't survive the labor cost increase because bigger, monopolistic enterprises have cut their available operating margin through means unavailable to an aspiring entrepreneur. Saying they don't deserve to exist is giving way too much credit to the incumbents in many cases.
There is another dimension to this that most people haven't talked about, remote and gig work. For most small and medium businesses, it's cost prohibitive to hire remote employees. For larger companies it's very easy. This has created a regional imbalance.
Lots of knowledge working and call center opportunities are moving to full time remote. Paying employees the same with better benefits to never leave their house.
