Money enables a lot of opportunities.
I went to university. My parents didn't earn loads, but they had enough money that they could drive me to Unis across the country for interviews. And they earned enough that if I was to get into financial bother while at uni, they could subsidise it.
They were also able to fund extra activities for us as kids, such as kumom, rainbows etc, tennis and athletic clubs, which are all part in parcel of opening the world up to opportunities that go beyond school, the park and the home which is sadly the breadth of experiences many in poverty have access to.
I remember being 12 and inviting a friend to a beach in Wales with me and my family for a day trip, that friend couldn't comprehended leaving the town for a day out. If your world is that small, it is very hard to break out if it. And I think it can be romanticised that you just have to 'dream big' to change your life, when in the real world its just not that easy.
It is not just support from parents though, a lot of success has to be enabled.
I am a health care professional. I have managed to start my own business which pays me significantly more than if I was to stay in the NHS, yes I worked hard. But I also had a partner that earned well enough to subsidise me for 2 years while I developed my business and wasn't earning much, and with no dependents and living in a cheap part of the Uk, it was fairly easy done. I am under no delusions that it was just hard work that got me where I am.
Being enabled isn't just financial though, I know many people despite how hard they work and what hours they put in they will never be wealthy as there are just too many factors stacked against them. And I think for those where everything has just fallen into place, they can't comprehend this isn't the same for everyone
