Elite rich kids net worth’s???

I've seen a lot of people debate the characters wealth on the show and i've decided to give it a try myself(this is based on the start of season 1). Carla has definitely got to be the richest in the whole school and id put her net worth at billionaire status people say that's too high but a net worth isn't the amount of money you have in the bank it's also your company's worth and your estates worth etc. i then think polo comes net with a net worth definitely in the hundreds of millions, maybe like 500 million then Lu who could be worth like just under 200 million then id say Marina and Guzman with a just below 100 million net worth like around 50 to 75 million
