Platinum and iridium are scarce resources. They are in high demand and have a high price. If we mine asteroids, we can get a lot of money.
Look at how much resources we are getting! Time to send some back to earth!
Sir, our platinum is VERY inexpensive. We want you to be our business partner.
But we have so much! And I need a way to pay my employees!
Don't you see?! Platinum is not scarce anymore! Everyone has what they need. Platinum is no longer a valuable resource. Now, leave my office before I call security.
NO! I cannot. We already have a business partner basically giving us whatever we need for free. No one needs it anymore.
