Maria, there is great injustice in the world and a concentration of super wealth in the hands of a very few and suffering of billions and austerity for billions.
The super rich elite know that as the population increases, the injustice and the poverty and the wealth gap will only increase. They know that that the poor will demand water and food and resources and education and wealth, and tehy know that they themselves will have to relinquish a lot of their wealth in order to assuage the masses.
They could help the poor rise and help them grow in prosperity or they could try to curb and control the power of the people. Helping the poor to rise will create a bigger bourgeoisie with ever higher demands and expectations. I don't think that they want that, because it will eventually lead to a lessening of their wealth. They prefer the people to be held back under austerity with no growth or low growth, with expensive fuel and heat, and high costs of travel and movement. They want gas bills, electricty bills and water bills to rise and rise to keep the people down. They want deindustrialisation, closure of factories and manufacturing and mining and steel production. They want the people to have a service economy in a deindustrialised low-growth world. Then, when jobs are scarce and pay little, they can institute workfare schemes, and they can even put forward the idea that workers' rights should be reduced, that the minimum wage should be lowered, and that workers should be able to be sacked more easily.
The rich elite are pursuing a policy of neo-feudalism.
Big businesses will not suffer, they never do. It is only people who will suffer. The mega corporations may offer to pay a bit more tax out of the millions they turn over, but it will be the public who pay hundreds of pounds extra per year for the carbon taxes and who pay double-digit increases per year in fuel bills and rail travel bills.
The corporations will prosper and the people will endure austerity and low growth in the neo-feudal elitist world of teh mega rich and their trust funds, charitable foundations, think tanks and lobby groups.
