I was one of those teenagers at 13.
I appreciated the work training from early experience in the job market. The skills learned from getting mentored by the business owners for the small business I worked for as a teenager was invaluable as I got older.
I wouldn’t have traded that for anything. Teenagers now only get their head filled up with lofty ideas as to how it should work, then go into the market at 18 with no experience in a job, no employment training, and no real concept of what it means to actually work and run a business.
