There's a lot going on in your statement to dig through.
The article specifically says these car washes barely add jobs.. but let's ignore that.
When a business opens and starts to hire people, there is no guarantee it will exist long term. When a person applies for a job, they need to do some due diligence researching the business to see if it sounds like something that will be around as long as they want to have a job.
Are you proposing we shouldn't allow "risky" business to start and hire people because there is no certainty they will be around in 1-5 years? Of course that doesn't make any sense.
If a business fails, people will lose their jobs, but that is not a reason to prevent business from starting. In fact, if we did prevent them, those jobs would have never existed!
