I work 40+ hours a week in quite a stressful job full of deadlines in a very uncertain industry and guess what for.....£18k......my partner also has a very stressful job doing on average 35 hours a week, I say on average because a lot of the time he has to travel the country.....and guess what for £22k......
we own (mortgaged) our house we don't rent, we don't get a single penny in tax credits, the only thing we are entitled to is child benefit....which yes, even at £20 a week is a massive help. I am currently 28 weeks pregnant and when I go on maternity leave I will only be picking up SMP...around £134 a week.
I would much rather be in your position and not be worrying how I am going to be able to afford to buy shopping for the next 9 months, then how I am going to be able to live after paying for childcare when I come back to work!
as for your comment, "People who earn just over 50k are generally the work horses in skilled jobs that ecomony needs to grow. Given that such people will be saddled with high student loans in the future, what will senior teachers, doctors gain from all their hard work?"......I am the lowest paid in my office as I am not long out of uni, yet I seem to be doing the most work with very little benefit, all the running around included. and yes I do have a student loan to pay also, it may not be much at the minute per month, but it still has to be paid. I also have an hours commute to work.
spend a day in a low earners shoes then say that again......
