Sometimes I wonder why big corporations can even exist competitively as there is such downward pressure on productivity as they grow. High barriers of entry. In 99% of cases the barrier is either capitol requirements, government regulation or both. Or to put in other words, any business which can be challenged by a startup, will be. And it is only a matter of time until enough startups iterate through enough business plans until they find one that will steal your business. So either be productive or be behind significant barriers to market entry.
