My research indicates quite a bit of confusion and some complexity with this issue, starting exactly with what this border adjustment tax is and who is affected and who isn't. Does it apply only to US companies who shift operations abroad and then bring the product back here to sell it to us at a reduced price due to lower labor costs? Or does it apply to every product that is imported into the US regardless of where it came from or who built it? IOW, will foreign companies have to pay that BAT too? And, will a BAT be struck down by the WTO (World Trade Organization)? And, what will the repercussions be from those countries that are negatively affected? Also, I suspect some US businesses would be adversely affected too, like retailers that sell shoes and clothing and electronics that are made much more cheaply elsewhere and sold here. Obviously our standard of living declines if we have to pay significantly more for stuff like that if there's a big BAT tax tacked onto the cost.
Basic economics say that when the cost or supply (production) goes up, so does the price. And correspondingly the demand drops, that's ECON 101. So IMHO it boils down to winners and losers some industries and business sectors will do well but others will not. Supporters of the BAT will tout the winners and the opposition will decry the losers, with neither side telling you about the flip side. My general impression is that when prices go up due to gov't intervention (which is what a BAT is), the consumer generally comes out a loser, especially those at the lower end of the income ladder. Cuz your dollars won't go as far, simple as that. Some say that won't happen if the BAT results in a stronger dollar; personally I'm a bit skeptical about that.
