What is the most likely reason fast food companies want to advertise and sell their prouducts in schools

Explanation:

From my opinion, fast food companies want to advertise their food to children in school is to encourage the young people to eat fast food. if they do like the food the children will be brain washed into thinking fast food is good and will have them go to fast food constantly. They like this cycle because they can easily get more money and preying on little kids is an advantage because they don't know any better. this is why i think fast food companies want to advertise and sell their products in schools.
