To take just a single example: tariffs. It is true that if one were interested in re-growing a domestic manufacturing base, tariffs might be one tool you might use to help promote that (they also might not be). So now we have an administration that has actually gone with tariffs, but in such a ridiculous fashion that it is more or less certain that they will have no such impact on the US economy. Tariffs on! Tariffs off! Tariffs on! Tariffs off for my friends! etc. etc. In fact, the most charitable interpretation of the current tariff strategy is as a back door for more ass-kissing by companies and economic sectors.
The same applies to everything else they've done so far. This will not remove the tumor, though it may amputate enough limbs that the tumor is the least of our worries.
