Mexico is semi-peripheral country in the World-System. Why isn't it a Core Country?
This blog explores the question of Mexico' role in the World-System.
Eight Futures for Mexico The best future for Mexico would be Business-as-Usual (BAU), that is no Geopolitical alignments. Geopolitical with the US would produce a steady state while linkage with China (CN) would be the worst, creating collapse.
Latin America and the Donroe Doctrine US attempts to destroy the Rule-Based World Order and become a regional Hegemon involve dominating both North and South America.
Latin America Futures The best future for Latin America is Business-as-Usual (BAU), that is, no Geopolitical Linkages.
Why is it important to study Spain? Spanish Culture is a strong force in the Southwestern United States and, of course, in Latin America. The US Government understands none of this and would be an awful Regional Hegemon.
You can run the MXL20 model and other statistical models for Latin America here.
Earth System Complexities Needless to say, the World Environmental System has a level of complexity that eludes computer models and qualitative commentaries. Here's a simple flow chart.
So IAMS, paper-and-pencil calculations and opinionated blather are not good enough for the Skeptical Environmentalist? Here are results from my own, statistically estimated models:
There are currently bills before the US Congress and Chapter 24 in Project 2025 (the Conservative Manifesto) calling for the US Federal Reserve to be abolished. Google AI Reports:
The following reasons are given:
These arguments can be debated. However, what interests me is the argument for more Federal Reserve Transparency and Automation and I have been posting on that topic:
Trump vs. The Federal Reserve President Trump (and a lot of other politicians) want lower interest rates to stimulate investment. The Fed has been keeping interest rates above the Attractor path given Trump's erratic economic policies. And, there are lots of problems the Fed is facing in setting interest rates too low.
Four Regimes for Fed OS 1.0 The main problem with totally automating the Federal Reserve is what to do during Economic Crises. In addition to Business as Usual (BAU), three crises regimes can be identified statistically where human judgment is needed.
Over time, I will have a lot more to say about Federal Reserve and automation of other Federal Government agencies. Given the dismal performance of the Trump II administration and the mistake of Big Tech for support of Right-Wing Agendas, it is time to start thinking out of the box!
The United States is facing a large number of problems right now. And, it does not appear that the Trump II Administration policies are addressed to solving any of them. Here are the problems and their interconnections as reported by ChatGPT (see the graphic below)
Briefly, the Political System (top of the graphic below) has created economic, social, technological and geopolitical pressures that have led to declining state capacity. The arrows show reinforcing causal links that make the problems difficult to address.
Is the US in the Fifth Stage of Collapse as argued by the video above?
Results from the USL20 model (above) suggest that the US along with the World System (WL20 model) are to slow down and will reach a peak somewhere between 2040 and 2070.
A Blog Roll of my postings on the US economy mostly using the USL20 model follows:
Alternate Futures for the USThe current administration (Trump II) envisions a Business-As-Usual future of unlimited, unstable exponential growth. A more realistic Geopolitical model would link the US to the World System.
US CO2 Emission Reductions Unlikely The Trump II has done everything they can to disable Climate Policy and my forecasts are for CO2 emissions to stabilize at current levels (rather than be reduced) well past 2040.
Is the US in a Debt Crisis? The US has been in a Debt Crisis since 2010 (Debt significantly above the Attractor Path) but the future forecast is for peak-and-decline.
For the ULS203 Model, the primary state variables are:
The ULS203 Model is nonlinear and unstable but only has one eigenvalue > 1.0-- it is essentially a moving average model. The USL20W Model (World Model) is also a moving average model but is linear and can be stabilized.
Jan 5, 2026. After the Invasion of Venezuela by the Trump Administration, Brazil lined up as one of the Latin American countries that condemned the attack (here). It was also one of the Latin American countries hit hard by Trump Tariffs.
Coffee is a good example (graphic above from Trading Economics). In 2025, Trump imposed tariffs on Brazilian coffee and prices in the super market begin to rise and Trump's approval ratings begin to decline. One November 20, 2025, Reuters reports (here) that Trump lifted the tariffs. Trump had been arguing that even though tariffs were taxes, they would be paid by the importers. That turned out not to be true (something Trump could have learned in ECON 101).
Here is a Blog Roll of my other postings on Brazil:
Seven Futures for Brazil Alignment with the US or the other Latin American Countries (LAC) is best.
I use my blogs to make informal comments on policy topics related to my research interests in the World-System, computer simulation of the US Health Care System, the US Economy, the US Stock Market, and the US Financial System. I am retired from the University of Wisconsin -- Madison. I have taught Statistics and Computer Science and also served on the UW's HIPAA Task Force and the Bioterrorism Task Force. I have also been a member of my local planning commission, a jazz guitarist and a golfer, so some of that may find its way into the blogs.
