Mine definitely did and I graduated year 12 in 2008. I was recently looking at the Facebook page of my old Catholic private school in a low socio-economic country Victorian town that I attended (when I went there it was a prep to year 10 school but it now goes up to year 12) and they have so much new fancy stuff that I definitely did not have while I was at school there. They have a school band with instruments, a bright big gymnasium and classrooms that are made of bricks (among other newer things). When I was at school, we only had the school choir (no other musical options), outdoor basketball courts rather than a gymnasium and portable metal classrooms. I remember the teachers there genuinely complained that our school was poor at time (because, being a school in the country, we really were)! I feel like I missed out a lot.
My partner graduated 2 years after me (different high school and area to me) from a public high school in the low socio-economic outer suburbs of a regional city in Victoria. Same situation as mine: their high school got new fancy buildings and other amenities that weren't previously there when they attended that school.
My partner and I feel that Millennials (and Zillennials) were the "transition generation" in terms of schooling: upgrades to buildings, teaching methods and technologies were happening towards the end of our schooling or just after we left school and we didn't get to benefit from them (or benefit only a little).
Did you guys get to enjoy the new fancy things that arrived at your schools? Or did you just miss out like we did? And for Gen Z: what did us Millennials & Zillennials miss out on in terms of new school upgrades?
