I am a millennial, although on the older side (early 30s) and I definitely see where you are coming from with that rant.
Many people in my age group seem to think the world owes them something. Their parents told them they were special, and they could do anything they want. When something goes wrong it could not possibly be their fault, and someone else should fix it for them. There are plenty of people like that in earlier generations too, but mine seems to be especially full of it.
I admit I was fortunate in many ways. I have parents who care (my mother especially cared enough to hit me or throw things when I annoyed her), I score very well on any test I care to take with very little effort compared to most, and I was born into a middle class US household which was not struggling.
I really think overly protective parents, schools which do not want to leave anyone behind, awards for everyone, college for everyone, etc. have caused a bit of a problem. The thing is that once you leave childhood and enter the real world, nobody really gives a shit about you except you. That is a nasty transition for someone who has been coddled their entire life, and not everyone makes it successfully.
As an adult it is your problem if your life is not going the way you want, and if you want to know who will fix it for you, you should go find a mirror.
People complain about crippling student loans, but they are the ones who signed the loan. They complain that they cannot get a job, but they lack the skills which would make them employable. They complain when they lose the jobs they do get, or are not promoted, but they are the ones on facebook instead of working. They complain that they are fat, but they sit on ass all day, eat mcdonalds, and drink coke. They complain that companies have all the power, but lack the motivation to go start their own. They complain about their huge cell phone bill, but for some reason though it was a good idea to sign up for a couple year loan so they can have an iphone.
I have made my way in the world without too much of an issue (the recession hit me just after forming a new company using my own money, which kind of sucked...but at this point that is over and done.)
I have a decent job because I have useful skills, and control over many aspects of work because I reliably show up and remain calm when things go wrong.
I have no debt because I avoid it when I think it is not in my interest.
I am not fat or diabetic because I eat well and run every morning.
That does not mean that everything has always worked out, despite what may many people think. I do get tired of people saying that I just lucked out, when what is really occurring is that I make changes in my life when I am not satisfied with the way things are going. These can sometimes be major and uncomfortable changes where I need to invest substantial effort and take some risk.
I see so many people saying that somebody needs to fix the problems with our society, but do not even consider that they should be that somebody.
