Yes I dont think thats whats making money in Europe. Deutsche Post is making money from owning DHL I think. Not that USPS buying fedex is likely. Closing post offices has reduced costs, delaying the issues. Here in the uk we are in a similar position to the US. There is a shift to banks and utilities sending by email, and junk is shifting to phone as it is more effective.

However merging and being profitable has probably helped some of these outside the uk be less government minded and more commercial.
