Final answer:
There is no one-size-fits-all marketing orientation for firms, as the diversity in consumer needs prompts a range of products in market-oriented economies.
Step-by-step explanation:
There is not one definitive marketing orientation or philosophy that can be deemed the best for all firms to follow. This is because market-oriented economies are designed to serve the varied needs and wants of consumers, and therefore the diversity of products reflects the diversity of those consumers. It can be argued that excessive product differentiation and the associated costs in advertising may be socially wasteful, leading to a discussion on the optimal amount of variety needed in the market.
However, defenders of market-oriented economies posit that no one is compelled to purchase highly differentiated products or brand names, leaving the power of choice with the consumer. They also argue that product differentiation can bring substantial consumer benefits, as firms aim for short-term profits that in turn spur innovation and meet more specific consumer needs. The debate between the need for variety versus efficiency in marketing orientations is ongoing, complicated by the difficulty in measuring the 'right' amount of variety and the differing values placed on it by various stakeholders.
