A top 10% household income is £72k. That's not rich by any stretch of the imagination. There are many jobs in that bracket that would be deemed "regular" and "reachable" for many many of the working public, if they can be bothered.
A couple I know from Ghana working in supported living work 48 hours a week, 4 x 12 hr shifts. That's around £64k. If one of them choses to work one shift of overtime then be in the top 10% of household income. Oh those pesky, lazy immigrants. 😁😁
The top 10% of earners earned 31% of total income in UK 2023/2024. They paid 60% of all income tax collected.
Is that "fair"?
