Millennials hate Boomers for one reason only... They're jealous! They know their generation sucks, so they project. Nearly every notable pop/rock/metal composition was written and recorded by Boomers. We made the best toys, the best movies, the best television, the best music, the coolest cars... The list is practically endless. Millennials became so accustomed to unwarranted praise and handouts, that they think talent and ability are tangible items. As though "boomers" extracted talent and ability from some magical well, to point where the well is now dry. They are the product of Marxist-Socialist miseducation, and it shows.
On a personal note... We didn't have Guitar Player magazine and the internet to learn songs from. Learning by ear was a pain in the ass... but, the unrealized benefit was that we developed an ability to recognize and identify pitch. My grandpa used to say... "A dollar earned is worth more than a dollar received."
