That is NOT true! People build out after an area becomes overcrowded.....and move outwards. If you move into an area after those plans were implemented and factories were built....then that is not racism! If you had stayed in that area when you know all of this then that is not racism. No one is stopping people from moving....but it is in the interest of some politicians for the poor to remain in some areas for their votes.....whether that areas is polluted or not.....giving them just enough for them to survive but never enough for them to get out of rundown areas....oh and for that they get their votes! Lets look at America....who controls all of the ghettos and barrios in large cities...and has for decades? DEMOCRATS! And besides what specific areas are you talking about....You talk the talk...let us see you walk the walk!
