I'm pushing 40, so there's another 10 years to build up the cash/stocks/bonds/lending pot further, and another 15 to build up the pensions further (well, hopefully of course). Might even choose to retire before 50, since I'll have enough that I'll have the option of trading off yearly withdrawals vs working longer.
I think my point still stands: software engineers in Europe earn less than those in SV (and it's important to remember than SV is an outlier even on the US), but you can still live a very comfortable life, save a lot, and retire early (even if not quite as early as 50), all while working far fewer hours and living in a society that provides free healthcare, education (including higher education in Scotland) and unemployment safety nets, and where society looks out for everyone, not just "number 1".
Edit: forgot to also say that the company pension has not always been as great it is now, and to also mention that 2/3 of our pension pot is actually in person pensions (SIPPs).
