The US has 330m people, you generally (emphasis, as there are certainly exceptions) don't need to look beyond its labor base to find what you're looking for.
If you're in Estonia and looking to hire a software engineer for remote work, maybe you end up hiring someone from Poland or Spain. That's still EU hiring in the EU, more akin to what you're referring to with the US. On average the smaller the country, it probably increases the odds that more of the labor you're looking for is going to be outside of your own borders.
