Well the British economic problems are a bit more complicated than that unfortunately.
There are ex-miner/ factory workers whose job no long exists and they don't have any other skills to transit into other industries.
On the other hand, there are also geological restrictions, such as in land areas would struggle to benefit from international tradings.
And of course, there are issues with the benefits systems. Even being on benefits, quite often they struggle to manage their budgets and get themselves in trouble
