No, it actually didn't.

Capitalism was heavily regulated before Reagan and Thatcher. We also had mixed economies (welfare state and socialism) throughout the western world. Most of western Europe has retained that. For instance, Germany is a welfare state.

Also, the business world worked differently. The price of a produce was based on the cost of its production. After the entry of neoliberalism, it was changed to 'what the market will bear."

I've known about climate change since 1970. In the upper circles of education, it has been known about since the end of the 18th century.

There is nothing that can be done about stopping it now. It's here. The only thing we can do is prepare for the damage that is coming.
