The inequalities may be there, but even rather poor people (in the US) are quite rich in an absolute sense, at the moment. Radical green policies would cause real, tangible changes to people's lives; if you actually wanted to reach realistic climate targets, many people wouldn't have cars due to carbon taxes, electricity costs would be much higher, etc.

Someone indirectly advocating for such things while flying in a private jet is a pretty bad look. It reminds me of a medieval king gorging himself on food while telling the population to slim down.
