The bottom line is that many people had this as a benefit and now very few do. What's unchanged is most people spend less time thinking about their pension throughout their lifespan than they do about almost anything else you can imagine, but they really should be because it's all on their shoulders now.
Here in the UK it seems we have a whole generation a couple of decades away from retirement poverty.
If you do that throughout a career - keeping the same fund between employers - you have an independent source of income for retirement. By giving significant tax benefits to not withdrawing this money early, most people who worked most of their careers will be set for retirement.
> After a lifetime of saving, the average UK pension pot stands at £61,897. With current annuity rates, this would buy you an average retirement income of only around £3,000 extra per year from 67, which added to the maximum State Pension, makes just over £12,000 a year, just enough for a basic retirement lifestyle.
