I don't think so but I think there's easy access to unlimited resources which can make an idol a lot of money in the long run, when promoted right. Not immediately or a few years after debut.
I think active and successful senior idols are always richer than the younger and more popular idols at least until they are 7+ years in the business because of company profit cuts and less favorable contract terms not only about money but also about how idols are promoted and creative control. And I believe that the smaller the label, the more the successful idols earn.
I am bored so let's discuss money that is way more than I have because why not ![]()
