There have been lots of privatizations all over the Western world and most are not well known, its the negative examples that are very much talked about. And many or most are somewhere between fully private and fully public anyway, so the picture is much more muddy. I think to say its all a failure would be very reductive.

I think many of the telephone operator privatization worked pretty well in most places and buildup of user business for those companies and more competition, mostly from formerly public operators competing in other markets. But it also depends on the country.

Some of the airline privatization seems to me also sensible.

In my country (Switzerland) government owned some banks or partly old them and sold some stock in them, witch seems sensible to me.

Some water infrastructure was privatized and regulated in many countries and for the most part this has worked fine, maybe not in Britain.

Denmark seems to have done quite a lot of privatization and it was mostly considered pretty well done.

I was really surprised how much of this was done all over Europe, often by 'left' governments. Once you start researching you find more and more.

Would be the work for an economists thesis or something to try to do a full accounting of this across all European nations.
