The "31x" is a bit clickbait --the only way that's possible is 1) start with a really low number --most anyone could do this by digging into the first times they ever got paid for work or 2) have an outlier success, like a business exit or liquidity event.
This guy grinded his salary up to decent ranges, starting from an arbitrary low point.
> I went thru the regular Swiss education system eventually starting an apprenticeship in IT in one of the biggest telcos in Switzerland and doing the professional matura at the same time during these 4 years.
So I'm sure there's a ton of highly-paid SWEs that did work part time at McDonald's at one point. They might have an even better multiplier.
...but all that said, grinding away and getting raises & promotions, combined with saving & investing a significant proportion of that income, is basically one of the few classic ways to repeatably build wealth. It works, but to suggest this to people is like suggesting to exercise for better health.
