Taking you at your word, then perhaps meditate on whether "Start a political party and fix it" is the kind of statement which would motivate an activist. In my experience (and I've donated literally years of my life to supporting and nurturing creative people), asking questions and listening, truly expressing interest in people's ambitions, is more effective than shaming people for not having taken on ridiculously unrealistic goals.

And by the way, I feel plenty satisfied that contributing to open source software in just about any capacity helps to ameliorate the problem of economic inequality, by empowering individual creators without harming capital -- and inequality is what's at the root of this tax issue.
