The link is interesting but the political message is quite a bit forced. Urban decay and urban renovation exist anywhere. A similar portfolio could have been made in years past in districts of New York, Rome, London, Buenos Aires etc.

Many of those buildings were publicly owned (by the state, or trade unions, or whatever) and fašade polishing was not a high priority in East Germany. Their promise was to give a house and a job to anybody. They did keep that promise. At their own game, they were not failing at all. Germans wanted to change game, which is fine, but the critique to East Germany on the playing ground where it did not play is unfair.

They were giving a house (a small apartment in a huge grey condominium, still is a house) to anybody for basically nothing, while in the Western world most people have to pay for 30 or 40 years to buy a house, or pay a rent which costs a substantial amount of wage, and when they don't pay we have a domino effect which is still sinking us.
Maybe in these sad days where 30% or more of youth is unemployed and have the nightmare of providing for house and children we should humbly recognise that Communism did take a lot of angst away from life, and that for many people (not for me) this is worth more than political freedom or the dream to become rich.

I am a convinced liberist-liberal pro-capital pro-free market visceral anticommunist person but to be frank I find a certain anticommunist propaganda preposterous.
