They are big capitalistic industries that were well established in the market, and right-wing tends to think that free market is a good thing and that state should not constraint the market. Right-wing politicians tend to be more friendly with successful big industries leaders, either because they are part of their circle or because they see successful company leaders as deserving to have a bigger say in the political decisions. Right-wing tends also to be conservative, so be less in favor in socio-economical changes.
