Noted. But I have two kids who went to preschool. (At the time, we were a two-income household so we managed to pay the cost of private preschool.) Beyond the self-regulation and socialization goals, as my kids mature, I am able to trace their habits back to those very early formative years. My son became a self-directed learner with a passion for reflection and logic. I still have clear memories of him at age 2: when Mom had a problem or didn't know something, he used to say "Go find out about it!" My daughter became a self-directed learner who solves problems. At 4 months, she was the youngest member of her nursery school, she ended up doing everything early and, yes, often got herself into trouble (climbed inside the dryer at 8 months!). But now, when she faces difficulties - a F on her first AP Calculus test - she tackles it with determination and hard work; this carries her through school and work. As a Mom who is a teacher, I could not have done all this without preschool.
