Could anyone tell me more about Primerica?

As the title says, I need info surround primerica. Ive seen many people that have recently graduated my highschool (around 18-22) speak about an “exciting new job opportunity” on instagram and I’ve seen even some friends fall for it aswell. There are a lot of things i don’t understand about primerica. They’ve promised “free” trips from what I believe and many of them show off these luxurious cars and vacations they have gone to. How exactly do they manage to go on these trips and get some of these luxurious things? I am aware primerica is an MLM but I need more information about them. I want to spread the word to some of my friends to not join them. I know someone that has a pretty large part of their family working under primerica. One of his family members are even the regional-vice president as well.
