I actually disagree with you on the fact that to be a daycare provider you don't need a skill set? It takes huge transferable skills to do this job well. The same goes for teachers a piece of paper is never going to make you a great one, it's dedication and a love for the student. There is a HUGE difference between quality daycare vs cheap daycare.
Yes anyone can open up a daycare but to be successful at it is a whole other discussion. Look at the movie Mr. Hollands Opus, he started out just doing it for the paycheck but he realized that in order to get through to his students he needed to give a dam.
I have been in and out of the "customer service" industry for 25 years and let me tell you if you don't like it you will burn out fast and become substandard. Sorry don't want that caring or teaching my kids!
