Does anyone else think 3% return isn’t that spectacular?

But that's not the percentage return on investible assets. That's the increase in his net worth in a year.

Think about the typical upper middle class retiree who might have a 401(k) worth $1 million and a paid off house worth $500,000. If they get a 10% return on their portfolio, their house price appreciates by 5%, and they get $10,000 in social security income while their spending rate is $100,000/year, their net worth would go up by $100k + $25k + $10k - $100k for a total of $35k, which is only 2.3% of their total net worth. Even though their investments did pretty well that year.

Bezos is getting more than 3% return. He's just spending a lot of it. Like on a $55 million wedding.
