The amount of money that sports stars earn is a very controversial subject, and many people have different opinions on it.
On the one hand, there is a lot of poverty in the world and a lot people who don´t work so it isn´t very fair that one person that only works for a few hours a day earns so much money.
On the other hand, sports people train very hard and make a lot of compaines thousands of euros. They also give us entertainment.
Summing up, they earn too much money but their career is very short so they have to be paid more.
