I am thinking that the 3 countries you had mentioned are the 'vanguard' of the 'isms' in the western world, not because the populous there initiated these ideas -- but because these places are chosen to be the 'test grounds'.

Sort of like it is easier to have biolabs or other testing facilities, in other places... to test out how those yet-to-be-fully-backed ideas will work out, without incurring costs of a 'blowback' in the financially-and-election sensitive places..

After all, the introduction of laws, the supporting 'academic research', and other elements -- will need to be built out...

Cashless society is another idea that will be implemented in the 3 places you mentioned, first.
