The US Congress is practically able to pass only a single giant bill every year. To work around its own deficit rules, these bills are packed with taxation time bombs where rules have expiration dates or delayed starts several years in the future.
Then, if Congress doesn’t get around to defusing its own time bombs, you get situations like this R&D expensing fiasco where American businesses and employees pay the price. Unless the bomb is hopefully retroactively cancelled, like happened now.
On top of this madness, there’s an executive branch operating like a runaway autocracy, producing a flood of executive orders that intentionally flaunt laws and even target specific private entities (e.g. Trump’s attacks on law firms that worked for his opponents, and universities he doesn’t like).
How long can a nation function like this? If the bond market loses faith in this process, there could be mayhem. Will be interesting to see if the passage of BBB impacts US debt when markets open again on Monday.
