The fall of the wall

When the Berlin wall came down 20 years ago we who lived on this side of it had freedom of expression and freedom of movement and, on the whole, governments that had some respect for the will of the people.
Fast forward to today. We have a government that spies on us constantly, personal expression is restricted, parents are not trusted to bring up their children, fat people and smokers and old people are subject to discrimination, elections are rigged by the governing party where they can, mindless bureaucracy increasingly dominates our lives and corruption among the elite is commonplace.
What really happened?
