I start it with neoliberalism which really picked up steam with Nixon. But even Clinton and Obama were neoliberals every president since Nixon was neoliberal just with different social issues (divide and conquer the plebes). Globalization and exponential consumerism.

before 1990 you buy a phone like corded even cordless and they still work today if you have a landline.

Now I need a new phone every 3 years. All electronics are made to be replaced not to last and that just makes business sense but not very good environmental sense.
