Earlier quoted context omitted.
I have a pension from my tech job. Almost all professional full-time jobs offer pensions. It might be in the form of a 401k in the US, but a 401k is just another kind of pension.
They're both forms of retirements savings, but a 401k is a totally different form of retirements savings from a pension.
Wikipedia say it's a pension:
> a 401(k) plan is an employer-sponsored defined-contribution pension
https://en.wikipedia.org/wiki/401(k)
The US Code also says it's a pension - 401 is 'Qualified pension, profit-sharing, and stock bonus plans' and 401(k) is covered under the 'qualified pension' clause ('qualified' meaning the same as 'defined contribution' in this case.)
If it looks like a pension and quacks like a pension and is called a pension in law and is called a pension in non-technical resources like Wikipedia then... it's a pension!
