The problem is, the tariffs weren't always paid by consumers.
About 50% of the tariffs collected were absorbed by suppliers cutting their prices - are you saying those suppliers should be repaid? Or that they should jack up the prices they now charge customers to make up for the losses they incurred?
About 25% were absorbed by the business themselves - they were not passed on.
The remaining 25% were passed on.
Now, it's likely easy if it was a product manufactured in China and sold as is, but if it's a more complex supply chain - say, raw steel from Canada, imported into the US (tariffs), then made into products down the line it gets more complex - the importer paid tariffs, then they need to rebate people down the line and by the time it gets to you, who knows how the price was affected - someone might have absorbed the price increase, someone else jacked it up because "tariffs" to make more profit, etc.
Now take it as a car part - raw steel from Canada, cast in Canada, machined into parts in the US, assembled into an engine in Canada, and put into a vehicle made in the US. It crosses the border multiple times, incurred tariffs and reciprocal tariffs And now things are twisted so tightly a forensic accountant will take years to untangle the effect.
In the end, just like the whole trade disruption, it's a huge mess. Lots of price jumps were due to people simply blaming tariffs as an excuse to raise prices rather than tariffs themselves. Others choose to absorb the increased cost at lowered margins.
Jeff Bezos wanted to show how much tariffs would add to the price. We thought he chickened out due to Trump - but maybe it was also because refunds are going to be much more opaque - if people knew they spent $100 on tariffs in total, that becomes a paper trail where they would want that $100 back.
