eeks yes. I am a scrimp and save person and many people say to me "oh the economy will collapse if everyone does that".
But surely an economy built on people buying stuff, and overpopulation, is a house of cards anyway? I've been in the habit of scrimping and saving since I started earning - I once took peanut butter and banana sandwiches to work for lunch and a boss genuinely took me to one side and asked if everything was okay!!
so I'm not going to start buying stuff I don't want and haven't got space for - but increasingly I see that people are taking on that kind of mindset, also for environmental reasons.
in terms of "services" - what do you mean? I prefer not to do eating out etc. I sometimes can't avoid it due to friendship circles and London distances, but wherever possible I have people over to my place and cook. What else comes under "services"? Probably they will always be propped up by the mega rich?
Ali yes, the employer contribution can be a thing but I've never had any of the impressive options I've seen described here. And what I have been asked to put in is too much. And I did start very early with the scrimping and saving. And I don't think the tax benefit is that great unless you are a higher rate taxpayer, IMHO. It's all risk and balance.
