It is simple.  I sell medical equipment and supplies.  The existing supply chain has been all but destroyed by a sudden overwhelming demand from all levels of our society.  Imagine suddenly the demand for your products or services overnight jumps  50 to 100 times what it was the previous week.  It happened.  How would you respond?  Could you respond and satisfy all those customers? Could your suppliers in a few days supply you with a hundred times your normal supplies?  Do you have the staff to do this and satisfy your customers?  Who do you know that walked around with a mask on  last year?  Or kept bottles of sanitizer on their desk?  Very large buyers from the government to the large hospital groups have  captured large amounts of these supplies.  The normal supply chain supplying smaller or independent doctors, surgery centers and clinics suddenly could not get anything.  Factories went to shipping 10-20% of their purchase orders.  Now new suppliers are entering the picture but it takes money, time and staff resources get set and started not to mention the cost of inventory.  Additional funds give you the resources to apply to your greatest needs such as staff, rent or to open these new supply lines.  It gives you the flexibility to survive.
