If money is not an issue, would you enroll your baby/kid in a playschool? Why or why not?

I'm considering sending my son to play school. That's not going to happen until about one more year but as a mom, I always want to make sure that he is ready for everything, including the big school. It's not just an assurance to myself as a paranoid mom. It's more of him knowing what he can expect when he starts going to school. The kind of interaction that he will experience with other kids will improve his social skills, motor skills, confidence and he may start to have a sense of responsibility. I heard friends say that sending him to school too soon will make him feel bad about going to school later on. I beg to disagree since playschools work differently.
