I used to feel the same, but eventually I came to understand that they have a tremendously important role in the business ecosystem.

Like sharks in the sea or wolves in the wilderness, they identify and remove sick and ailing businesses. Additionally they offer a convenient exit to tired owners and investors, thus incentivizing further business creation. Finally, they identify and exploit regulation-created monopolies, enabling the government to re-allow competition through deregulation - something more and more important in today's populist and regulation-happy climate.
