I've called you out on your ignorance with this all or nothing view, several times.
But let's do a wee figure experiement since you seem to think we are living in 1992 with the worth of these salaries.
Teacher on £40,000, single parent with two kids. Monthly figures:
Take home (if they contribute 10% to their pension for retirement) £2,461
Deduct
Average rent for a 3 bed in Glasgow - £1,200
Average council tax - £140 (low banding, poor area)
Average utility bills - £167 (very reserved, I have two kids and we are £240 a month)
Mobile phone & broadband - £60
Average food bill - £330
Car expenses (fuel, insurance, maintenance) - £200
Less than £400 leftover a month.
Being quite reserved in estimates and not even including things like leisure, clothes, holidays, childcare, Christmas and birthdays and an assumption of an owned car.
You're living in la la land if you think a £40,000 salary is significant in 2024 for someone with a family. One emergency and that hypothetical person could be in a foodbank.
But hey, easy to adjust? Why don't you show me how?
Maybe they buy instead of rents... Oops, housing crisis by successive governments not building enough homes.
Downsizes? Three people in a studio flat possibly?
Gets rid of the car, doesn't buy leisure stuff for the kids, doesn't have a mobile phone herself?
Maybe the person could "adjust" by forcing one of the kids back inside her.
So basically a relative salary that would have been quite comfortable 15 years ago, no longer is because of government policy. Unless the person happens to be Mystic Meg and knew their wage would decline in such a massive manner under the Tories, easy adjusting is hardly guaranteed.
You really are one of the most ignorant, disconnected individuals that I've ever came across.
