The world is becoming more and more prosperous and everything is getting better in the long term.
The only reason why a 4% SWR currently has a higher chance of failure are the high US stock market valuation.
For me personally 3% is the new 4% as long as we have those high US valuations and I'm planning to live from my investments for 45-50 years.
Next to VTSAX I mix some higher yielding Vanguard VYM ETF, some Vanguard REIT ETF, some single REITs and some higher yielding Singapore+ Hong Kong Index ETF (plus Lending Club and Fundrise) and then I simply live from the dividends including some safety margin.
Never sell any stock, never run out of dividends.
