I save a reasonable amount usually 1/4 of my salary since finding out I am pregnant that has increased to half I know I'm fortunate enough to be able to do this.
But we also live pretty frugal and I'm careful with budgeting. Other than mortgage nothing is on finance, rarely buy clothes, phone contracts are no more than £15 a month, shop is £35/wk for 2, no gym membership etc. I'm not bothered about having the latest gadgets or a shiny car ours is 14 years old. If we want something then we save the money for it.
My DH has suffered 3 redundancies in 6 yrs due to companies going bust so I got used to being on a tight budget. Although I now have a better paid job I'm still in the habit of being skint.
I agree it's a low wage high cost society which is a massive contributor but I also think payday loans and credit cards have a lot to answer for that people can have what they want pay later attitude.
Along with the attitude that kids/adults need the latest gadget, phone, big TV, sky and its perfectly acceptable to put this all on credit and then wonder why they struggle or can't save.
I see this within my own family, my nephews and nieces receive ridiculous birthday and Christmas presents which my brother definitely can't afford, the kids don't need it all. They end up paying shed loads in interest and call us flash for going on holiday which we have saved hard for.....
