You knew what the price was when you paid for it. You weren't misled. What's the injustice?

Yes, it's a windfall for the business, and it would be nice for them to pass it on, but unless they promised to do it, that wasn't the deal.

The injustice isn't that consumers were harmed (this is just the nature of public policy with both winners and losers), but that our legal system does not accept that tax incidence exists and is giving taxpayer funds to businesses for no reason.

I don't know what world you live in where an arbitrary and illegal price increase on essentially everything is "just."
