“All corporate costs get passed on to the consumer.”
Not really. They’re constrained by what their competition chooses to try to pass along. They try to pass along what they can, but they can’t pass it all off. If they could, why would they care about taxes or try to carve out exceptions in the tax code? After all, they would just pass it on to the consumer.
In order to be profitable then revenue has to be higher than the combined total of ALL costs, which means that any profitable company is passing ALL costs to the consumer. They care about taxes just like with any other cost, there’s no guarantee the consumer will buy at higher costs, which I said later in the post which you apparently didn’t bother to read far enough to see. Of course what happens when the market won’t bare the increases necessary in the price for the corporation to pass on all costs is the corporation loses money, then they eventually go out of business.
