The rich will always choose to live somewhere nice.They have the power.
Those of modest means have to compromise.
The area may be rough and polluted now,but pollution is under attack thank goodness,and we will in the future live in a less polluted world.
I am thinking of the Hull docklands.When I was a lad the streets around the docks in the city centre were awful.Crime,violence,prostitution,and stunk of fish,rotten fruit diesel etc.
On a recent visit,I didn't recognise it as the same area I had known when I was younger.Old warehouses converted into rather swish apartments,and the whole area looking clean and fresh.
Don't know if these apartments are "affordable"or not,I would hope that they are.
