The market leader has a huge advantage over his competitors. He has capital to buy them up. He can use Microsoftian strategies to lock customers into his products. He can use huge advertising budgets to persuade customers to pay more for inferior products. He can buy off politicians to rig the laws in his favour.
Capitalism has a short term outlook.
It difficult to attract money for example to develop a new antibiotic that may not be needed for another decade, but which will take seven years to create. We may even know that such an antibiotic will be desperately needed in a decade. There are too many other projects competing for capital with a faster payback. We will run out of fossil fuels in a mere 30 to 60 years, yet capitalism is incapable of getting on with the long range preparation needed. It tends to only look ahead about a year.
