This question already has an answer here:
Why is the British passport the most valuable despite colonization? is a discussion of which passports allow the most visa-free or visa-on-arrival entries. That kinda has me wondering what the most open country is. ie. which country is the most universally easiest to get into, regardless of what country you're coming from.
Like just because UK visitors can get into a lot of countries without visa's doesn't necessarily mean that all their agreements are reciprocal and that just anyone can get into their country without a Visa. Or are visa free agreements always reciprocal?
