I certainly agree based on my previous statement that income is not wealth, but I was trying to make two points and mixed the messages.
One is that amounts of money that were once considered an unbelievable amount for income or wealth - say $100k and $1m - have now been eroded by inflation to fairly modest money. In the 70s or 80s, having a million meant never working again. Earning 100k a year when a house cost $50k was huge money, and might lead to wealth quickly, if one bought several houses with it.
Another point I’d like to sneak in is that there’s almost no modern equivalent to that kind of employed income. On paper, inflation puts it at 400k - so maybe today’s equivalent of a surgeon - but the 50k house now costs $500k-1m. Notional inflation being 4x, while the critically important things have gone up 10-20x means that something harder to quantify is broken, and upward mobility isn’t working the way we expect. The same opportunities don’t exist. We are less likely to turn income into wealth over time than at points in the past, and so the tendency of people to erroneously think high income = wealth may have a reasonable basis in history that has never been less true today.
Edit: and it’s not just houses, it’s the stock market. The advent of the internet and e-commerce resulting in tech stock growth 1995-today is a phenomenon not likely to be replicated in any other area. We may be running out of growth to be had. The ability to get 10-20x your money over 30-40 years of investments is probably gone, and with it the prospect of comfortable retirement for even relatively high earners.
