So, a couple of trillion upfront for Europe's part of a decarbonised economic future, whose states have splurged on massive green economic infrastructure and managed to sustain social wellbeing in the interim, so the children of tomorrow breathe clean air, live in solar/wind powered clean houses, cheap and plentiful subsidised education and work in clean industries, at the cost of some temporary price increases and a higher tax rate down the line (maybe), is somehow worse than continuing toward environmental destruction, circling the wagons around private wealth (and lower tax)? Read some Marx, at least understand what alienation is.
Future generations are the ones getting fucked over, because they are the ones who will have to pay for the subsidies you're wanting for your pet project.
It's clear you haven't got a clue of the actual long term effects of your proposed policies. I recommend you read Basic Economics by Thomas Sowell, if only to understand that the policies you propose will have consequences.
