Yep, that is a really huge part of it. All sorts of reasons - other costs being higher (housing etc) so not enough disposable income to save, general ignorance about how much saving is required to secure a reasonable retirement etc etc. There's also distrust in pensions, which is why, as someone working in the industry, I am at pains to correct inaccuracy such as some of that quoted by @stewski above which, if taken at face value, would leave a reader with the impression that 'private pensions are high risk, underperform and everyone in financial services knows it' which is quite simply garbage. Scaremongering like that puts people off saving.
