I was talking specifically about the alleged "national jealousy" in sports, in particular figure skating.OMG! Maybe you didn't understand me. I mentioned the "national jealousy" in sport not in general in civil life. I hate it there! I live in a country where my goverment pours lot of foolish nationalism to the people's head. And it works, unfortunately. The "national jealousy" ( my poor english doesn't allow to explain it more or to use other term) is exist and totally natural. Most of the people support their countrymen ( and of course, there are favorites from other countries, too) and if they see they have no new stars, their skaters have no chance will be jealous...and start to criticise the succesfuls. (You don't start to refute this because there are exceptions always)
Only those conditioned to view everything through the prism of nationalistic sports pride, would accuse others of national jealousy.
No, it's not natural to "feel jealous if there're no national stars" and "to start criticizing successful ones" because of it. That would be insane - in a normal non-propaganda environment.
