Not sure why 2019 specifically, it's 2024. I think you also underestimate 1980s Israel - although there was a stock-market crash in 1983, it was not otherwise that poor- maybe more like today's Portugal or Greece than Venezuela.

But anyway my parents were 1983 Israelis, they didn't come with future-Israel purchasing power - so they were able to afford their housing on the income of the time :) Other kids in my class had ± similar housing. Some were poor and had worse housing, but not 5 people in a 62m flat level of poverty- for that to be common you had to go back another couple decades (e.g. my mother's childhood experience in the 40s-50s was more like that, might have been common up to the 60s).
