Why is there so much Generation Hatred: Baby Boomers, Gen X and millennials

I am a big history buff, and from studying some of the accomplishments made in the last 100 years, I feel that generation blaming is a fruitless exercise.

Every generation has had to deal with different problems with only the resources available to them at the time.

For example, I am in my mid 20s and I personally don't use social media much outside of YouTube. However, if Facebook were invented 40 or more years ago, many of people who are 50+ now would have used it as adolescence.

As for the complaints about problems, I will admit that I have had to make a lot of self-inspection about my problems in life and how to resolve them. I realize that personal responsibility and not having a defeatist attitude is one way to overcome them. But some problems the millennials face are not completely of their own doing.

So I have some questions

1) Is college just as costly now as it was for Baby Boomers and Gen X (scaling for inflation)

2) Are companies as willing to hire recent high school graduates in 2017 as they were in 1960 to 1985. Were the barriers for entry level positions the same now as they were then.

3) Given this is a post-racial society (legally speaking) do you feel that the influx of minorities and women in the workforce may have caused a higher supply of labor thus creating more competition and lowering wages.

4) Is home buying more difficult for the average American and if so is it due to economic conditions post 2010 being different from 1960 to 1985.

TLDR. Are the economic conditions of previous generations the same as they were for post 2000s.

Any references or links would be appreciated.
