Rule of thumb for a retirement portfolio is to withdraw 4% per year. 4% of $1M is $40k. People survive on 40k/year, but you’d be considered pretty low income in most areas.
Big point being that in the US we have many cost of living expenses that the UK does not (or rather, you get it via your taxes)












You know the difference between a millionaire and a billionaire? About one billion dollars.
But yeah, like the other commenter said: $10m puts you WELL outside of working class. That’s enough to retire on anywhere on the world, and with a high degree of luxury outside of a handful of the most expensive cities. That money, invested by anybody with half a brain, will make enough money per year than many extremely skilled professions make. We’re talking doctor salary without doing any actual work. They’re not buying senators wholesale like billionaires, but their house rep probably knows them by name.
