Sure, but you still need to go there to work. You need money to buy a car, and you need the car to get paid. Of course, some vultures will lend you a couple of quid to buy something, but then the astronomical interest rates just add up to your problems. And pray that nothing unexpected happens, like the unreliable car you just bought for £500 breaking down before you finished paying for it, because then you don’t have a job anymore and it takes weeks to get support from the government. And good luck you if you have children.
Also, people who can’t keep up with bills are not going to have easy access to the Internet either. There are libraries and such, but it adds yet more friction and stress. There are loads of things you don’t necessarily realise if you haven’t been in such a situation or really thought about it. Every one of them is not a huge problem in itself, but it all adds up.
Mental aspects are also important. People familiar with symptoms of depression and chronic anxiety know how debilitating they can be.
It definitely is not impossible to get out of poverty, just very hard.
