Tldr: educated people, scientists want change, economists clearly speak out, with evidence ranging from Math, over models, to irl examples form history and present, FOR a much heavier taxation of wealth, more social programs, workers rights and market regulations. It is just that this gets shut up, people get too easily manipulated and people who want to bring change sabotaged by those who have power, money, influence.

Long version:

I don't remember where i have this following statement from:

To see unfairness, having the willingness to bring change and then see it threw, you need to be selfless, charismatic, (politicly) connected, determined and smart.

The once calling for change, the scientists, are smart, determined and often selfless but rarely charismatic and politicly connected.

The average politicians are charismatic, connected and sometimes determined and smart. But not selfless and their intelligence is in tricking people and not self reflection and long sight.

A vast majority of humans are reactionary, impatient and driven by egoism or atleast not selfless enought that they'd give up something small that others have it better. All problems we are facing all over the world can be boiled down to one stem cause: greed. That caused all these ripple effects. But when true peoples servants (or those that want to be it) try to fight the root, the once benefiting from the system as it is right now, try with all power to undermine and sabotage these efforts. Unrooting the tangled web of problems, one thred at a time, takes a lot of time and effort, because it is harder to untangle a gordian knot than to create one. But many humans, because of their impatience and selfcenteredness, want easy and quick solutions, that dont change the way they life. This ofc is not possible to be given so, the once promising this, will win every time. But those types of people speak nothing but shallow words.

The solution to this character problem would be education. Lots of it. This would break the cycle, however this goes against the interests of the once controlling and benefiting from the cycle.

It is not that there is no drive for change. No call. Look at history. Climat change has been an issue for over 60 years. Even in 1853 the first prediction was made that "so much [polution], on such a scale can not be good for the world" talking about the smog from all the factories of the industrial revolution. So many generations! So much time! Has anything been done despite all being aware this can cause extingtion? Nope!! In fact Shell HIDE SCIENCE EVIDENCE OF CAR EMISSIONS CAUSING HEALTH PROBLEMS AND CLIMAT CHANGE! The warning was in the 2000s "if we breach 2°C global warming there will be no way back." Right now, we are at 2.6°C. And instead of doubling down, after having a devistating flood every year in central europe, europes forrests burning, hail and drought levels that destroyed entire harvests on mass in europe, EU is thinking about getting rid of their ban of fossile fuel car sale and production that - if it were up to science - should have already gotten in effect in 2020, got then pushed to 2030, then to 2035, - germany is putting a cap on Renewable energie from wind turbines, after in 2018 having put on a cap on solar energie due to AND I QUOTE "The sun will not always shine, it will die out one day and so why should we invest in a technologie that soon wont be useable anymore"

Greed and money is what forces science to shut up.

Sorry for that much text
