It does, but that trust is established top down. If businesses in this country act lawlessly with impunity, why would you expect people, especially if they are suffering because of some company's greed, to be the chump who acts nobly while seeing a society that rewards theft?
That is not a normative moral defense of this behavior, just a descriptive one. Why would anyone expect a normal person to see a company receiving a tariff refund for a tariff that person paid and then view stealing from them as a continuation of the theft that the company itself engaged in by not paying them back?
