McDonald's marketing towards children

I thought that the idea of gearing marketing towards children was very disturbing. The way that McDonald's developed the the character Ronald McDonald to bring in more business towards children is very low. I think it's terrible the way that children want to go to McDonald's now because of the toys they put in their meals is terrible because most parents want to give their kids everything they want and to make their kids happy they bring them to McDonald's and allow them to eat the low quality food that is filled with chemicals and hormones. It's taking advantage of both children and parents.
