There is the obvious way that environmentalism increases the economic divide. When you raise the price of coal or oil or natural gas, you make sure that people with low incomes have less of it and rich people have as much as they want. You increase the ticket price for commercial airlines where it affects ordinary people but the same plane carries rich people in 1st Class for whom the price makes no difference.
The less obvious way is in daily behavior.
In a fancy hotel or bathroom in an expensive setting you will find pressed cotton hand towels. In an ordinary public place you will find the hand blower to dry your hands.
On a private jet you'll find all sorts of environmentally expensive arrays of food services and supplies that will never be found in the coach cabin of a commercial airline.
Environmentalists make sure that San Francisco airport has people waiting for hours because the airport cannot be expanded. Expansion is banned for environmental reasons. But successful travelers either have their own plane timeshare or own a private plane or they can land at another nearby airport and have a limousine transport them to their destination.
The list is long. The gist of it is that environmentalism falls hard on ordinary people but has virtually no impact on the rich. Environmentalism increases the economic divide.
