Let&amp;#x27;s say you move into a new market, trying to undercut the status quo. The status quo, with their power of scale and experience can just undercut you back. Who is benefitting from this? The customers! So if the customers want more competition they have to pay you to play. Which means they have to co-invest with you and promise to buy your service later.&lt;p&gt;A good is example are the Apple iPhone screens. If Apple wants a new competing supplier, they have to invest in new competitors.</text><parent_chain><item><author>throwaway9878</author><text>Everybody with more money than you can always undercut you in anything you ever do so why bother ever trying to do anything</text></item><item><author>arcticbull</author><text>Here&amp;#x27;s the issue.

I would agree that there needs to be other differentiators in addition to cost, which could provide sufficient moat against other competitors, big or small.</text><parent_chain><item><author>throwaway9878</author><text>Everybody with more money than you can always undercut you in anything you ever do so why bother ever trying to do anything</text></item><item><author>arcticbull</author><text>Here&amp;#x27;s the issue.
