I don't know that it should be legal to buy a company and then pay for it by loading up the company with debt obligations. It seems like a form of value destruction in order to enrich a bunch of vultures.
Fundamentally it is basically saying maybe we could buy this company and then plunder it with some % chance that it will still stay afloat and keep generating profit after they gut the company to try to service a debt that should not be attached to the company at all and provided no value to anyone but the vultures.
