There are many reasons for the distinction, culture and money being chief among them.

Dubbing is far more expensive than subs. So countries like Germany or France would be more likely to afford it. They're also countries which try to promote the use of their language for historical and national pride reasons (as opposed to Anglicization of everything) so it makes them even more likely to have dubs. They also had dubbing for so long that it became cultural and maybe even expected.

Contrast that with countries like the former Eastern block which had no foreign material to speak of until the '90s, and when they finally did they couldn't afford dubbing, so they went with the quick and easy route of subs. They also probably have fewer aspirations for the promotion of their own language and priorities practicality over pride, embracing foreign languages faster.
