Growing up in the '60s and '70s among six kids, we were each sent into exile upon graduation from high school. We were upperish middle-class, then lowerish middle class after the parents divorced.
My mom was Depression Era and from second-world culture. She expected her kids to contribute labor from an early age. She wanted us to be obedient, vacuum, and not drop acid. She worked her ass off. Don't get me wrong; it wasn't like the Death Camps of Tarzana at home. Dad just wanted us to bareback. So there was that.
For the first half of sibs in the '60s, it was mostly about getting rid of out-of-control, promiscuous hippies, who weren't interested in college. Also about making room for her bf(s!), and single rooms available to the growing next set, to keep the peace. There were multiple, radioactive sibling rivalries. For that generation, it was possible for a white kid to get a job, share housing or have a studio apt., and opportunities for college.
Once single, my mom pushed the rest of us out for economic reasons. Each time, we moved to a smaller apartment. As the youngest, I ended up in a 3-room flat in a shitty urban neighborhood with my mother and her latest alcoholic husband. Wanting to get the fuck out, I did well in school and got a partial scholarship to the first university of my choice. Parents promised to support but did not/could not deliver.
By then, times were tough: the economy tanked, interest rates and tuition rose exponentially, as did real estate/rentals in my area. I worked and took out loans. Took me 10 years to get my B.S..
My mom was a really nice woman who had a difficult life and allowed herself to be controlled by men. It was not her decision to have so many spawn. She really didn't have our backs, nor did our crappy father. But there was always food on the table and a warm place to sleep... until age 18.
So yes, kicking kids out can happen. Reasons vary. As "adults," each of us were mostly alienated from our parents for at least a decade or two. She was over being a mother and crowd-controller. Meanwhile, she finally got to see the world, and she deserved it.
Fortunately, over time, most of us evolved and became great friends until mom died.
Although I had to sometimes live in freaky rooms in scary neighborhoods and sometimes out of my car at a young age, I made it. The experience led me to become the gorgeous, pointlessly bitching and hissing eldergay that I am proud to be today. So, obviously, no regrets here.
Except for one idiot brother, my sibs each had 1 child only and they are doting parents and/or helicopter grandparents. My nieces and nephews are awesome, grateful, adults, who grew up with the confidence that their parents have their back and who will do anything for their parents when that time comes. This family structure is more like the Asian and European paradigms.
OP, be grateful that your parents are providing you intelligent guidance and at least some of the means toward a college education. No love is unconditional absolutely. Sorry. We're all human -- even your parents.
Hope you take your question along with you to any sociology, history, psychology, anthropology course requirements you might take. Human family structures have taken some twists and turns!
So, goodnight, Billy. If you're a good twink, you'll post a picture of your naked self -- only if you're over 18. If someone touches you inappropriately and you don't want it, don't say yes even if they promise to send you to Harvard in a Camero.
