Outside of the 1 in 1 million "jobs" like rock star and professional athlete, there are ways to make 400K (finance, c-suite in a business, small business owner, partner at a law firm, some types of doctors, some type of dentists, etc.)
It just takes a while to get one of those positions, and it's obviously very competitive.
Even then, at 400K, assuming it's not capital gains, and living in NYC, you're going to be left with 200K after taxes.
It would take about 15-20 years after you reach one of those positions to save up for a place in Tower Verre, from my perspective.
The great thing about Verre is its greatness is visible to all- even those not wealthy enough to live there.
