I have a good salary (6 figures inc bonus) but never really allowed for lifestyle creep as am naturally pretty easily pleased, drive a 10 year old Clio, live in a small bungalow etc... Not a single one of my acquaintances could guess what sort of income I have.
During COVID I got into the FIRE (Financial Independence Retire Early) movement and became even more focused.
So have been contributing really aggressively as my pay has risen. Even through paying for two kids in childcare etc..
Unless we have a 1920s style market crash, I'll check out from workforce as soon as I can get my fingers on my pension. Possibly earlier as am building up my stocks and shares ISA too.
There's a few factors at play here for those relying on DC pensions - ability pursue a well paid career (which has an element of luck and privilege and I don't know what will happen in the future with AI etc), and a mindset focused on long-term goals and delayed gratification (which comes easily to some, and some can learn).
Work colleagues and friends around me have much more lavish lifestyles, the cars, the houses, the constant new kitchens, sofas, excessive holidays etc... And as all of that has to be paid for from post-tax income, it probably equates to at least £20k of annual pension contributions as these go pre-tax (especially stark difference as higher rate tax payers).
We still do holidays as a family of 4, run two cars, eat out etc... So it's not a life of misery, just more a life of two people on £40k pa rather than much higher salaries.
I think a lot of higher earners are totally sleepwalking into poor retirements and wrecking the planet along the way with over-onsumption.
