Yet another White Male. Salaries are actually from multiple different countries, but I've converted all to GBP (as that's what I think in, mostly). Which has varied in value a lot over the years, so probably take it with a grain of salt.
1997 £18k First real web-dev work
1999 £60k Contract developer making the most of the dotcom boom
2000 £45k First attempt at running my own business (didn't go well)
2002 £28k Took a job that seemed stable and came with visa
2006 £40k Last permanent job
2008 £90k Working for myself part 2 - much improved
2014 £10k Had daughter - buttoned off work big time for a couple of years
2016 £50k Still doing my own gig, but better work-life balance
2018 £115k Working much harder than I’d planned. But enjoying it. Combo contract/own gig
For a data point when I started in 1979 at a world leading R&D organisation in the UK I was on £1620pa :-) about a 1/3 of the rate the scientific civil service was paying.
Though my first job at 15 was working in the local library as a shelver for 35p an hour
