This is indeed a very controversial statement because the rich are living a lifestyle which is at best unsustainable for the planet. They emit more greenhouse gas into the atmosphere for their own lavish lifestyles. They exploit poor labor conditions and lobby against every minor improvement. They don’t contribute to our shared funds like regular people, decreasing the state’s funds for more infrastructure which would have created more jobs. And they cause stress with their increased wealth disparity. Many research has shown perceived inequality is a significant stress producer. We may very well be bettor off without them.
