Why would it? What would it genuinely change? Nicer food? A better car? A nicer holiday? The only thing it changes is security. What exactly would be different?
And my salary isn't important but it's not 120k..... And now I'm in my 30s I realise how empty it is. It doesn't materially change anything.
Everything would be different for a lot of people.
First of all you have several members on here moaning that they cannot afford a home. Now it would be easily possible.
You could afford the absolute best area to live in that would be a substantial change to most people. Where their kids can then also go to private school and get the absolute best education possible.
Not everything is about Lamborghini's. There are lots of life changing things you can buy with money.
House, location, education, life insurance, health insurance, better quality of food, better quality of everything, £3k on a mattress as an example would be easily done and your back would thank you for it.
No stress, easy life.
