I never had the opportunity to go to preschool, or kindergarten. When my kids went, I realized that preschool is mainly to teach kids to enjoy school. What a wonderful way to start your education!
Fascinating research, but the results are not all that surprising. Conquered people do not generally have the wherewithal to up and leave the country if they don't like their new overlords. And Britain isn't exactly heralded for its class mobility in the centuries since.
My mom collected Green Stamps when I was a kid. Then in the '80s, I shopped at a grocery that used them, which was so weird by then that I started collecting them myself out of nostalgia. I got some nice small appliances, but I don't recall exactly what ones.
Things are so different now. My dorm had 260 girls, one TV, three channels. No one watched it much. We had at least a dozen phones, one at end of each hall, but a call had to go through the school switchboard, so they could make sure we paid for any long-distance calls.
Not too worried... we have five TVs at home, and she doesn't watch them. The youngest, on the other hand, watches TV constantly. And still aces her classes. She will eventually reach her limit on multitasking.
