Hardware suppliers and retailers won't go bankrupt because of this. They're doing great. Literally anything they put on the shelves will sell immediately.
If you're patient and follow stock alerts, you can get hardware at (or near) MSRP but it's a bigger pain than I've experienced in nearly 20 years. I have a reseller account with one of the biggest distributors in the US and still, my monthly quantity limits are very low (2 each CPU/GPUs for AMD and Nvidia and a more generous limit on Intel CPUs). This is despite having to make a significant minimum order every month just to maintain access.
Demand is high, shipping is under heavy pressure, tariff exemptions expired in the US on consumer electronics from China which alone accounts for 20% higher prices by itself.
At the beginning of the pandemic, many people put off purchases but then with so many more people bored and wanting to game, working and attending school remotely, the need for PC upgrades and additional systems is very high.
While the mining firms aren't helping things, they are not the main problem or even the biggest cause of component shortages. Retail miners with 1-2 GPUs mining on the side are not the problem at all. Retail miners are just making the best out of a bad situation and recouping some of the funds that went towards inflated hardware prices.
