Why millennial adults still act like children?

I noticed how the generation Millennials have not mentally left high school. I have noticed most people in their early 30's love drama. I mean this are grown old adults age 30 and over. I have noticed that when a millennial does not get their way they throw a fit as they were a 5 year old child. At work the other day for example I got stressed out and irritated which leaded me to have an argument at the work place with this 32 year old guy a coworker seems to be more interested in being the cool manager to a bunch of college kids Gen Z instead of making more money and making big sales. I personally I do not allowed my employees to talk at work unless it's with customers and they better be taking care of customer service. It's all about the sales and winning the customer I told my employees. I got one complaint from a customer the employees are done on my book. Now I noticed this immature behavior with people my age category. I had noticed now a days we still have 30 year olds living under mommy and daddy's roof. Ridiculous how they blame today's economy from their lazy choices while parents still pay for their phone bills. Adults are no longer acting like adults anymore which is sad. If I am established it's not because of oh you I become lucky no. I knew better to save as much money as possible. I was working extra hours working over time while my class 2011 decided to be dumb and hit the clubs look where it got them to no where. Still we have 30 year olds partying clubbing and hitting the bars. I wonder why can't millennials just act like normal adults? You never saw this behavior with Generation X and Generation Boomers. What is going on with millennials generation?
