What is it about 20-somethings?

I feel like the reason why people don't reach their 5 milestone in their 25s is because of our generation. Our generation is different than before. People before are more of a family oriented whereas today where people are more into money and sex. Today, people in their 20s are less mature, they just want to hang out with their friends and just relax.  That's how we are right now but there are some people who want to graduate and get a good job before they hit 25. 

I think that sex is also the reason why people don't marry early. People in their 20s could have sex whenever they want to or at least it's easier today than before so people don't really care about getting married and have sex. Before, couples need to be married and then they could have sex but now they could have sex and then get married.

Another reason why people in their 20s mature late is because their parents are helping them pay bills, food, rent, etc. If parents are helping their kids pay all their stuff, they're most likely to mature late because they think that their parents will help them for life and they think they don't need to work which results to having late responsibilities.

For example: my brother is 27 and he hasn't reached his 5 milestones yet because my mom has been helping her pay his bills. I think that if my mom didn't help him, He would have work harder to reach his goal and be mature faster.
