Your "statistical anomaly" is not anecdotal, it's the very symbol of a broken system that was designed not to care.
In this situation, I cannot expect the non-wealthy to make big efforts to reduce their consumption while the ultra rich continues to casually destroy the environment. We're letting the rich take almost all the profit but we ask the poor to work harder only because they're more numerous. This can only end with violence or a catastrophe, IMHO.
How about we start by putting a $1000/flight tax? Seems only fair that the rich, mobile class start reducing their emissions. After all, it's actually the upper classes that consume (by far) energy in gross terms.
It'd be hard to tax private jets, so much like the EU has just done with fuel duty, they end up exempting the super-rich and hammering the working class with more taxes.
