Here's the solution if you think someone is trying to rip you off by jacking up prices: go to the bank, borrow several million dollars, order equipment, build a plant, get permits and insurance, hire employees, and get to work fixing the problem! More supply is the solution to the supply/demand equation! See? Easy!
No, the solution is simple, but not EASY!
First, you've got to be someone the bank considers worthwhile to loan those "several million" dollars to. And that includes being someone the bank considers solvent enough to make the payments during the SEVERAL YEARS it will take to get your new ammo plant up and running, before any profit can be realized.
AND, one also must assume that the current situation, counting everything involved, does not significantly change while you are building your plant, waiting for delivery of special machinery, hiring and training a workforce, obtaining the needed raw materials and government approvals and every thing else in the millions of small details involved.
A change in fuel costs and transportation capability can screw your budget easily. It may take the government years to review and finally approve the Environmental Impact of your proposed ammo plant. The list of things needed is huge, and quite literally, you're going to be bleeding money for years until you get ALL the details working, and then, on top of that, are the ups and downs of the free market.
Additional complications come with marketing. Suppose you do manage to get your new plant up and running, and suppose Murphy happens and a batch of less than perfect ammo gets past your QC.
Somebody on U Tube gets it, tells the world its crap, and suddenly you have a couple million tube-heads telling the world everything you make is crap, don't buy it, and telling them that 24/7 365 days a year....
Possible that might have an effect on your bottom line, too...
Sure, the solution to the issue is simple, meaning its straightforward, but
doing it isn't easy. Or cheap.
