Like I said, those who cares already tried. And it has been proven that it isn't enough. The politicians know very well how the environment is and what will come out of it. They aren't stupid. But let be honest here, if your ultimate goal is to be reelected, would you raise tax and implement disruptive measures that does not bring immediate benefits? Your policies would get scrapped within one term by your successor.
Looking at the data we know that drastic changes are coming and they are inevitable. There is no realistic way to avoid it. You can tax all the companies to bankruptcy tomorrow and it would change nothing. That is a fact. So what is it that you propose to be the solution today? Personally, I think it is cruel to make people spend the last of their few years suffering for nothing instead of letting them enjoy it. Either way, we will all suffer in a couple decades anyway.
