I agree with @Halloumiheaven ’s point I'm not saying any of it is correct. But you have to wonder, our modern, 'right' way of doing things (and our generations do so arrogantly think we're always 'right' and 'progressive' )..is it all working out well?...
It’s not working out well (for many reasons). Dual income households are a necessity now in order to ‘just’ scrape by, rather than a choice made by the family in order to maximise income or because both parents want to have demanding jobs.
I have known many singles and couples who have sacrificed a lot in order to penny pinch, but some of the ideas thrown out on page 1 (forego a phone, sell your car) are very rarely feasible. Giving up your mobile phone would make life 10x more difficult for very small financial savings - if you can’t check emails, sign job offers on the spot, log into online portals on the go, you’re not lending yourself to being the ideal employee/job candidate/prospective tenant/loan applicant - should that be the case? No, but it is. People want things done quick and will not wait for you to get to the local library or home to your laptop. Plus, you need a mobile number to get verification codes for everything.
Being car free would be great, but people can’t rent in the areas they work in because it’s too expensive. They need cheaper rent to save. Public transport (where I live anyway) is not going to get you from A to B. If it did, that would be great. Lots of people do forego their car to bike to work, but a car is generally needed for so much more than just your job. Older, beat up cars are also subject to crazy insurance prices these days. When I got my first car a few years ago I wanted the oldest most crap model I could find but I couldn’t get insured on anything older than 8 years!! I cried at the amount I had to pay, and I didn’t want to spend it.
