The US tax code is absolutely riddled with tax loopholes. Many of these loopholes were designed to act as an incentive, such as tax breaks for hiring former felons, building factories in certain locations, investing in R&D etc etc. Major corporations often pay far lower than the US corporate tax rate precisely because they respond to these tax incentives (and sometimes abuse them, but that's a different story). Does this deal mean that the US will close these loopholes? If so, then 'rich nations' have lost a major tool for creating desired outcomes. If not, then how can this deal prevent other countries just offering whatever loopholes they want that reduce the effective tax rate below the minimum?
