A brutally honest and blunt explanation of the forces at play. Well done!

On tariffs, these have been used as a weapon to gain concessions from other countries. Slapping tariffs on many goods allowed the Americans to negotiate lower tariffs from other countries. Lower your tariffs and we’ll lower ours. Its about negotiation leverage to obtain a fair playing field. A fair playing field in turn allows you to do business with who you wish, the very system you said you crave.

On the left vs right though, your thesis has one major flaw. The right is trying to impose various things, but it is those things that it craves, and pretty much only those things. The left however, craves power. They openly speak about packing the Court, abolishing the border (to let in illegal immigrants they believe will vote for them), allowing illegal immigrants to vote, nuking the filibuster, adding two more states that will be reliably blue and more. They want to win the next election and then use it to ensure that they can never lose an election again. I do not see such speech coming from the right, nor have extremists in their party been winning primaries. Mamdani got three elected in New York alone, and with no one running against them, they will automatically be in Congress. There are a dozen more spread across the US, some of whom do not get that automatic pass. But the most visible one is in Maine where a man with the longest list of disqualifying behavior I’ve ever seen in a candidate, nonetheless won the primary and is leading in the poles for a Senate seat.

Danger. Loud, clear, ugly, and on the Left.
