I get your point. It's sad that for example football stars get millions a year while the people required to run a country don't get a good pay. But large parts of a society for example highly value those stars which is why they're so well-paid.

How’s that not a bad thing to reward people based on?

In an ideal world we could do that, but only because you put a lot of effort into something doesn't mean it is of higher value to society. If its standard stuff someone else could do or you just aren't better than many others you don't get valued as much. If everyone worked the same job (Its a ridiculous example, I know but stick with it one second) and worked their ass off it would just be nearly worthless since all the other jobs would be empty. Thats how the economy allocates the work force.

Nordic European countries have rather decent social welfare, agreed, but their economy is as sustained on unequal exchange as those of the rest of the developed world. In the case of Norway arguably more since they’re oil exporters. My point being, not every country, not even most countries, can be like Scandinavian countries because they rely on exploitation of people outside their borders.

This might be true, but even more industrialized countries like Germany or the Netherlands have a decent welfare state. They export a lot as well, yes, but I don't see it as much of an issue if the other countries were more industrialized and had higher pr capita productivity which would leave more things for everyone involved.
