SIPPs are beyond my lifestyle.
For a higher rate taxpayer you put in £60 and get £100 in your pension.
You can also do salary sacrifice and reduce you income tax and NI lability
It's quite likely that some people today will end up paying higher income tax rates in retirement than today.
And you can use drawdown to manage your income from the pension and you would of course make use of income from your ISA.
You seem to be arguing that saving for retirement is futile. You can invest is (almost) arbitrarily low risk to principal investments like US treasuries. I probably wouldn't advise that as the sole investment strategy for most people. But it is one way to reduce certain types of risk. (And most defined benefit plans have the same risk with respect to inflation.)
It's always surprising to me to see those huge companies stopping payments and the story ending there
You don't even have to know much about the system to understand how this works.
Defined benefit - Your pension is X, determined by rank, years of service, etc.
Defined contribution - While the above conditions may still apply, the bottom line of how well you do is determined by how much you put in on a regular basis.
Not hard to imagine why most companies made the switch or simply stopped offering traditional pensions - they're really expensive over the long term.
In UK and Ireland, though, most retirement plans are called "pensions", even defined contribution.
The first time I told my mom about pensions after moving, she said "oh my god you get a PENSION?!??" like it referred to the paycheck for life her parents got from the paper mill.
It's just semantics.
