So now conman switches his story again. Surprize surprize.

He said packers are generous from time to time by not manipulating the markets now he switches to they want all the profit they can get all the time.

So we go back to the question if they can manipulate the markets and want to do so why don't they?

They can't. That's why.

A packer having times of profit doesn't prove they manipulate the market.
