Bluntly speaking, as a taxpayer of country A I don’t care if country B benefits. It’s okay if they do but as a taxpayer of country A I wouldn’t like my money to be spent on solving country’s B issues.

I agree with your general premise, though.

Some truth to that on a national level, but what about the communal level? Wouldn't your whole nation be a better place if its counties didn't have to spend money for solving the same problems over and over again (and put the money into other infrastructure instead)?
