There are no third world contries inside the EU and EU-rules only apply to EU-members, i.e., when you sell a product in EU-contries, so your whole argument is moot. That being said, yes, not everything the EU does is fantastic, but there are tons of really good things that the EU made happen and the British government are utter dumbasses for their Brexit and many many Brits and other Europeans will now suffer the consequences.
But wow, the next topic derailed into a political discussion. Maybe we should start enforcing stricter on-topic rules.
