Why?

A really stupid question :

why does "conventional wisdom" (what's in a word ?) require that (small) countries be cut into even smaller pieces, while companies never can be large enough ? Globalisation of economics and atomisation of politics ?

Are there different rules for the management of a country and of a company ? Greed excepted of course ...

Economic and financial forces ( = greed) grow ever larger, while political forces (in theory = general interest) dwindle into insignificance.

Believe you me, the world is being taken over by the Mammon.
