I don't go around making negative comments about people on benefits, I don't know what everyone's circumstances are so can't judge.
Having said that, I came from a working class background, had a paper round from 12 yrs old, summer jobs from 13 working picking strawberries and other soft fruits at the farm a 4 mile bike ride away, weekend jobs from 15 and worked 25 hrs a week in the evenings all though a-levels and university.
First in my extended family to go to uni, didn't get to finish my degree as my mum died very suddenly, dad was already terminally ill. Continued working but moved to full time.
Got married, we eloped as didn't want and couldn't afford a big shindig, bought a very cheap house in 2010 which was the best we could afford with no help, kept working and saving so we could afford a baby which happened in 2014. We knew we wouldn't be able to afford more than 1 child in childcare so decided that we would be content with one child.
I went back to work when DD was 9 months old, childcare was twice the cost of our mortgage every month which was crippling. DH and I lived on the cheapest food, no treats and worked ourselves ragged to manage until DD was 3 and we got the 30 free hours.
Now nearly 8 years later, because I went back to work and was able to continue to progress we are financially in a really good place. My salary has quadrupled, we have no childcare costs, still in the really cheap house but we've been able to start to afford improvements. No plans to move because I'd rather pay off the mortgage early and fully own my house then end up with a bigger mortgage just for the sake of a fancier house or postcode.
It does frustrate me that other people get to spend so much more time with their children when young because they're being subsidised, but ultimately I also know that the route I chose has put me in a better position in the future. If DH ever leaves me then he'll be worse off but I'll be fine, if I lose my job then my experience and connections put me in a good position to find another one quickly, and the career I've chosen is typically a WFH role so I have a bit more contingency in case of long term illness/immobility, if not then I have the better part of a years net salary saved to tide me over, if either I or DH die we have insurances and investments that will look after the one who lives and see DD right.
I really can understand why some people feel resentful of people who are on benefits if all they look at is the present and a surface view of for example a mother spending all day with her kids. Especially if they are feeling sad about constantly feeling like they're rushing about, dropping their kids to other people and working, then sorting the house at 10pm because it's the first chance after getting home, doing tea, baths, bed, finishing up work emails.....
