And that's assuming your argument is true, which in general it isn't. If you raise prices then some of your customers will go elsewhere. That's why sellers don't raise prices already. If you raise prices and your competitors don't, even if your customers have extra money, people can still count and a dollar is still a dollar. The profit-maximizing strategy isn't to raise prices, it's to expand capacity as quickly as possible (which in many cases is immediate) so that you can make your existing profit across more customers who can now afford your product, without losing them to competitors with lower prices.
