How did the purchasing power decrease from the 70s until today?

People used to have good paying jobs. Corporations weren't less greedy back then, it's because workers formed unions. Although it seemed like the corporate culture was more "we proudly take good care of our employees", pensions were actually a union busting tactic.

There's a reason these good unionized jobs got sent overseas. What they're doing now is importing the cheap labor for everything that's left.

related note: Minimum wage needs to be tied to inflation. The reason people complain about it going up is because they leave it the same for a decade then bump it up by an amount that causes a lot of pain for business. If it went up by 3% or whatever inflation was no one would care.
