As a wealthier person (income of ~1m/year, give or take), I could not more strongly support Mamdani (no 'h' in Zohran's last name afaik). I want a candidate like him in my city to vote for.
If you're still measuring wealth by income, you're probably not in the bracket that is being discussed here. $1 million per year is an extremely comfortable income, but it would take 30 years of saving that, post tax, before you hit $30 million in net worth, which is the entry point for UHNW status.
I do see your point, but it's highly unlikely that they are putting their wealth into a HISA for 30 years. There is likely 0 people who got to UHNW through saving money.
