I think it's just very capitalistic.
Look you need money and/or protection, else you go bankrupt. We can provide these but there is a cost. And since you cannot refuse, we get to dictate terms... Our terms are "a controlling interest".
Alternatively we allow you to go bankrupt and then buy the bankrupt organisation for even less.
And instead of breaking your back ploughing fields.. you now fuck it up in a desk chair.
