Boomers haven't really accomplished anything generationally other than screwing up everything their parents built & fought for. Boomers lost every war they fought, are sucking up a larger share of resources, and are refusing to recognize or get out of the way of those who are trying to make changes. Boomers are determined to trash the "house" on their way out. The sooner they're gone, the better.

Really enjoy this podcast. Guest are questioned often if Mike's view varries from theirs. Always learning something new. I always take the guests speech with a grain of salt until I can verify if what they say is true or not. My rule of thumb, if a guest uses "rightc after making a statement, they are trying to push influence in their behalf, so their credibility should be questioned.
