We must prevent repairs in order to maximize shareholder profit in order for the wealth to trickle down in order to allow consumers to replace their nonserviceable goods.
How trickle-down economics works:
First, the shareholders get all the profits.
Then what?
...that's it.
The trick is to shove money at the shareholders faster than they can bank or consume it - this way, the overflow will spill down to the lower tiers of society.
