I really dont think there's anything good about a recession at all. When "bad companies" go down people lose their jobs, the economy takes a hit, social security costs rise and everyone hurts.
I don't really understand what worthless competition is either. "Worthless competition" is surely a contradiction in terms. If they were bad/worthless they wouldn't be competing.
Think about the http://en.wikipedia.org/wiki/Broken_window_fallacy if marketers get fired and become factory workers then the output of goods can increase. If factory workers are fired and become marketers the output of goods decrease. In total it matters what people are doing even if a person cares less about what their job is than the fact they have a job.
When I said 'worthless competition' I surely was thinking about General Motors and its total lack of innovation, compared with korean and japanese car companies.
