Wasn't it on MDC that I read this? Perhaps not.
It started with inner city kids from working parents being behind those who had a stay at home parent. (1970's)
So, preschools were created as part of the head start program.
Parents who could afford it wanted preschools for their kids, too, so the preschool business boomed.(late 70's)
Then programs started competing for tuition dollars (or the local currency), and preschools began advertising how they could di so much more than both other preschools and parents.(1980's)
Enough time passed with those messages bombarding parents, and
. Parents begin to believe they cannot compete with preschools.
I wish I had the source info. I'll see if I can find it again.
