It's Mexican exporters that pay the tariffs. Some of the cost is passed on to US consumers - if they continue to purchase Mexican goods.
I think neither theory nor empirical data support your idea. I dont think you account for real exchange rate effects, impacts on supply chains, impacts on domestic prices, impacts on real GDP, impacts emloyment, real incomes, or the actual effectiveness of the policy.
"What does the macroeconomy look like in the aftermath of tariff changes? We estimate impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963‐2014. Tariffs increases are associated with persistent economically and statistically significant declines in domestic output and productivity, as well as higher unemployment and inequality, real exchange rate appreciation and insignificant changes to the trade balance. Output and productivity impacts are magnified when tariffs rise during expansions and when they are imposed by advanced (as opposed to developing) economies; effects are asymmetric, being larger when tariffs go up than when they fall. Results are robust to a large number of perturbations to our methodology, and hold using both macroeconomic and industry‐level data. "

"This paper explores the impacts of the Trump administration’s trade policy on prices and welfare. Over the course of 2018, the U.S. experienced substantial increases in the prices of intermediates and final goods, dramatic changes to its supply-chain network, reductions in availability of imported varieties, and
complete pass through of the tariffs into domestic prices of imported goods. Overall, using standard economic methods, we find that
the full incidence of the tariff falls on domestic consumers, with a reduction in U.S. real income of $1.4 billion per month by the end of 2018. We also see similar patterns for foreign countries who have retaliated against the U.S., which indicates that the trade war also reduced real income for other countries."

"We analyze the impacts of the 2018 trade war on the U.S. economy. We estimate import demand and export supply elasticities using changes in U.S. and retaliatory tariffs over time. Imports from targeted countries declined 31.5% within products, while targeted U.S. exports fell 11.0%. We find
complete pass-through of U.S. tariffs to variety-level import prices. Using a general equilibrium framework that matches these elasticities, we compute the aggregate and regional impacts. Annual consumer and producer losses from higher costs of imports were $68.8 billion (0.37% of GDP). After accounting for higher tariff revenue and gains to domestic producers from higher prices, the aggregate welfare loss was $7.8 billion (0.04% of GDP). U.S. tariffs favored sectors located in politically competitive counties, but retaliatory tariffs offset the benefits to these counties. We find that tradeable-sector workers in heavily Republican counties were the most negatively affected by the trade war"

But this is in line with what economic theory already predicted starting [at least] with what Adam Smith wrote against in the Wealth of Nations. Trump's tariff policy is basic economic ignorance in line with the basic economic ignorance of AOC.

4.9 Tariffs – Principles of Microeconomics
But the tariffs are being imposed because they're not cooperating. If they can show that they're changing their policy, the tariffs can go away.
I'm aware of why they're being imposed. I simply think the reasoning is wrong.
Immigration issues affect us all. We're in this together, like it or not.
I'm not sure exactly what your point is. I'm not sure how you think "immigration issues affect us all" or why that effect means people have to "suffer financially" (as someone else on this thread said). I'm not sure why a policy of tariffs should follow from a vague belief that "immigration issues affect us all." I'm also not sure why you should require everyone to "be in this" with you to the point of harming people who don't think they're in this with you or don't want you forcing them into your boat. And I think it makes no sense once you consider the actual impact and ineffectiveness of the policy, which I don't think you will be able to argue against.
). It's ultimately US consumers that pay the price of tariffs - this is a new tax on Americans, not Mexicans.
