Note she mentions the 70's.

What also happened in the 60's-70's era?

Ever heard of John Nash - mathematician?
The Nash Equilibrium changed City Economics forever when they 'incorporated' this into World economic systems in 60's - a real 'game' changer.

This has lead to ever greater economic/banking crashes as the city 'whiz' kids game away and bet on commodities/cash/oil to make bonus (traders/bankers constantly caught manipulating(cheating) the markets as they play the game)

Reducing commodities to a bog (commode) standard since the 60's using the Nash Equilibrium and gaming the markets has reduced the city to a spread-gaming pile of steaming dung. (one etymology of 'Hedge' as in hedge funds = filth)
The prices of our food can be manipulated higher by spreading false rumours before the actual harvest results are known or the ordering of Oil tankers to sit in the Channel to create a temporary oil shortage to force petrol prices up.

The last time the City did this they killed hundreds of thousands in poorer countries who couldn't buy basic staple food(rice) any longer.

The Gaming of the economy is exactly the same as the fraudulant banking system conjuring money from thin air and charging interest (from the real producer slave workers) on it.

This allows those manipulating & 'gaming' the 'Gaming system' with insider knowledge (think scanda-louse Jєω SOROS who shopped fellow Jєωs as a kid to nαzιs to save his own hide) to make personal Billions!

In Hebrew, the word for 'economy' is related to the word for 'everything'
