To me, goverments 'green' measures are just patches that won't work, but are very likely to ruin the lifestyle of the middle class, while the affluent keep theirs untouched.
At the same time, the only real solution that is population decline, is 'spontaniously' happening without any policies like one child per couple, and so.
If the economics of an older population are much easier to solve than our progressive destruction of the environment... Why not incentivice policies to keep people childless?
