Thats because in central, industrialised countries, the agro is not the competitive sector, so they get protection. In Argentina the agro is the competitive sector, the one who provides dollars. Yes, we also have some industry, but its not the competitive sector here. In fact, the agro finances the industry. Industry does not provide dollars as the agro.
Thats why they get much more taxes than everybody, because is the other way as in industrilised countries. In fact, the protection they have in industrilized countries is from us. They subsidize the agro so they can compete with agrarian countries, such as Australia, Argentina, etc. Argentine agro does not need subsidios because they are already competitive without help, because of the advantages of the soil, the weather, etc
