In general what you are talking about is a Bill of Attainder and it is unconstitutional.
Notwithstanding the - not so clever - name of the Bill, it doesn’t exactly sound like anyone is being targeting so much as a legal framework is being proposed for recipients of corporate welfare to have to reimburse the government, based on corporate financials. Sure if it ONLY applies to Amazon there is a problem, but that isn’t likely.
Seems to me when you have employers like Walmart who rely on taxpayers to subsidize their employees benefits and simultaneously are the beneficiary of 20% (or $14B) in taxpayer funded food stamps annually there is a problem. Basically you have a single low paying employer who has dug a $14B taxpayer moat around any potential competition which would potentially drive up wages.
Shouldn’t lawmakers be able to look at employers as a whole and say...wow certain companies are really taking advantage and benefiting from corporate welfare and we need to take action to close the unwanted and unforeseen loopholes? I don’t think anyone is looking at Bezos and the Waltons and saying how do we target these rich people, they are saying these welfare programs are not fulfilling their intended purpose and the program needs to be re-evaluated.
