Of course they would - that's what they tried to do with medical supplies. They held back on what was happening in Wuhan so they'd have time to make contracts around the world to buy up OUR medical stuff. At one point we were sending ventilators to China while we were doing without. Trump put a stop to that when he heard what was going on...
You betcha they would. Someone is taking up our production of toilet paper too. I don’t know how paper towels, napkins, kleenex and sanitary wipes can be in such short supply either. Somebody is buying them up, and it can hardly be blamed on normal shopping or hoarding. It has been a month now, you would think the supply would now be meeting demand. In a free market system you would think this would be a chance to make a huge profit. That doesn’t seem to be happening.
