Upper middle class is a flexible term, but I’d put $30k tuition solidly in the realm of upper middle.class range. And those that can afford $30k/yr in tuition certainly aren’t generally in the fund capital improvements range of income.
We have one of those types of school locally. Practically a straight up Japanese school, with all Japanese kids.
So that explains the mystery of TL closing shop, suddenly going from everyone making 30k to “1 million nt isn’t that hard to make per year…1 million nt a year in Taiwan is harder but doable.” I was guessing his dad was finally giving him money or something, and certainly didn’t pick “business with mafia involved uncle” on the bingo card!
