"Your example is doing fine and pretty average for a taxpayer in a professional job "normal" "hard working" person !"
To be frank, I find this sort of response quite ridiculous.
For a woman to be earning £75k is not in any way at all "pretty average" or "normal" - and the implication that anybody who doesn't earn that much is not a "hard working" person ! is really quite goady.
Statistics from the Office for National Statistics (ONS) show that a woman earning £75k outside of London is at the 97th percentile of female full-time employees.
What that means is that she earns more than 97% of all female full-time employees.
For those working in London, the figures are obviously a bit different. In London she would only (only?) be at the 90th percentile - so she earns more than 90% of all female full-time employees in London.
There is a rather sharp divide between private and public employees in London. Is she worked in the public/non-profit sector then £75k would put her at around the 96th percentile but in the private sector she would be at around the 88th percentile.
So here is a woman who, by any measure, is one of the top earning women in this country.
Although, of course, income isn't a measure of "wealth" as such. The ONS did a survey back in 2020 (so figures will have increased somewhat since then with rising house prices) and found that the median net wealth of a household in the UK in 2020 was £302,500.
It varied by region, the highest was the South East at £503k and the lowest median net wealth was in the North East at £168k.
So where do you put the cut off as to what is counted as "wealthy"? Who knows? The top 20% of households? The top 10% of households?
Well, here is the information by percentiles (I've included every 5th one). Pick a percentile that feels right for you.
