Hmm. A leftist/communist/socialist who’s against paying taxes? Back to reality. This guy was a nutcase CREEP willing to kill others because he owed back taxes to “Mr. Big Brother IRS man”. The rest is just a mound of excuses for his suicidal murder spree.
The issue was taxes, and as you say, he had a host of other problems not dealt with throughout his life-personal problems unresolved. Throughout this screed he writes about accountability- it is not clear if he held himself accountable for the results of his decisions. For example- after 9/11 he couldn’t fly?— why? And if he couldn’t why didn’t he get in a car and drive, like the rest of us- to go take care of clients. Second- why would he not have done a little research before moving to “cheapskate” Austin- he would have found out quickly that, even though there’s no state income tax, in his field prices are therefore kept low. If he then decided to move, he needed to tone down the lifestyle. There is/was a lot wrong with this guy and he felt a need to write down the excuse for his actions- as evidenced by his final behaviour.
