Just like everything else, the market will try to charge you as much as you are willing to pay.
It's why when the corporate tax cuts were significantly slashed a few years back came down, prices were not changed in any meaningful way. The same reason why if corporate taxes are raised, the prices won't change in any meaningful way.
Everyone prices the same way we do. We will take the maximum people are willing to pay, everything on top of our cost basis is profit and we like profit.
