Massive is relative. If you have $1M and need $40k to live on (4% rule), a 50% downturn is massive. If you have $10M and need $100k to live on, a 50% downturn still leaves you plenty of room.
You don't need generational wealth, you just need a enough that the general "rule of thumb" is way more than you'd ever need to spend. That can be amassed in one generation.
