Retiring at 30 after selling successful start-ups?  Ah, you are one of those but cannot see it.  If you have really sold successful start-ups you know that the venture process is often about creating a story of deceit and selling the lies to sucker investors.  So you retire as a leach at age 30.  Tell me, are the start-ups you sold profitable.  Were they ever profitable.  Did you share the wealth with the employees who made the start-ups work?  If you retire at 30 you are an elite.  You are at the top of society.  What are you doing about climate change that makes a difference except bowing to it?  I also sold companies and am still working past nominal retirement age because I enjoy contributing.  I think Trump was the best choice.  I have 4kW of photovoltaic on my roof.  The earth is an oblate sphere.  1+1=2e^i2pi.
