"Rich people are paying more taxes so they are doing something for our planet"
NOPE:
1) Swiss is not using all such money to protect our planet!
2) More money they earn, more they go to places where they need to pay less taxes, as you can see exactly in this picture (green). Red are places where you need to pay much more than average.
3) They pay taxes (if they pay that ...) just because they need to pay that!

So in conclusion: Rich people = more taxes != climate protection
