I think the reason LBOs are so hated is difference in utility between the capitalists and the community. The capitalists (PE, management, and lenders) are putting a boatload of money at risk to make an even larger boatload of money, and are empowered to take that risk. If the bet doesn't work out? They'll lose money (but probably have lots left over) and maybe their jobs if goes bad.
The community (workers, local suppliers, and governments) are seeing their jobs, livelihoods, and institutions put at risk, and they likely are seeing no reward for success. They are not empowered to decline the increase in risk, even though they certainly have a stake in the future of the company.
