People should be asking that question on a lot of life's essentials, where the "provider" removed it from the market only to sell it back at a higher price having added no value.
People should also be reminded that nobody forces them to buy any product for a price that they personally find to be unreasonable.
Yep, like we're seeing now with insulin.
Their needs force them to buy the product. If the only one who has it - because they hoarded it - is somebody offering it at an unreasonable price, then they're forced to buy it at that price.
Hand sanitizer is not an essential need for anyone; soap is more effective. Nobody is forced by their needs to buy hand sanitizer.
Hardly true. Some things are necessary (resulting in grave consequences for non-purchase) and may not have other suppliers or may be cartelled.
