Clever. Nothing to say but this I guess.
Please do explain, the need for repairs will always be there, therefore why can't everyone start their own car repair business?
Because everyone doesn't have the resources to do so. Starting the business doesn't mean you created the demand for the product or service. The number of workers in a given industry or marketplace isn't dictated by the business owner.
Employers need good, reliable employees as much as those same employees need the employer.
