Here are three major areas I see that Trump and his sycophants are weakening.
1. Education, the lifeblood of the future. Trump's policies toward public and private education are aimed at undermining opportunities for women and minorities to advantage white males. Today women outnumber men in law schools and medical schools. Trump aims to reverse those numbers by forcing schools to admit more mediocre white men and fewer well qualified women and minorities, thus threatening more dropouts by men not educationally prepared for the rigors of both professions and, especially for medical practice risking a severe shortage of qualified doctors, which is already a problem. Republicans in states have created a mess of public schooling by trying to siphon taxpayer money into private Christian schools, charter schools teaching white supremacy, and voucher programs for schools teaching anything they want. We are also experiencing a significant brain drain in scientific and medical research as US scientists move to other countries and international students no linger come here.
2. Economy. Trump's tariffs and his economic threats against other countries are causing problems in the US with higher consumer prices, deliberate weakening of the dollar that also causes higher prices on imported goods while also making US treasuries less appealing for foreign investors, some of whom have started moving their money into other currencies. In addition, other countries are starting to exclude the US and form new trade agreements without us because the Trump administration is seen as dishonest and unreliable. Trump's extravagant spending on military wars and excursions, his space-based Golden Dome fantasy, huge government contracts and benefits for AI titans, his self-enrichment from government favors, and tax cuts for the wealthy will continue to push the US even further toward inequality and total control by the 1%, which sets policies to benefit their wealth and risks sending us into a serious recession. Trump us increasing the national debt, risking a collapsed economy.
3. Deliberate destruction of alternative energy sources. The rest of the world is progressing in this area and we are regressing. Trump's war on Iran has shown the world the value of relying less on fossil fuels and mire on other sources for energy. We are propping up oil companies, not developing new technologies for renewable energy, and countries like China are surpassing us. We will not be building on and exporting our technology because it will be unwanted by other countries moving past total reliance on fossil fuels.
Obviously, Trump's wrecking of the federal government, attempts to control voting, and his flouting of the law will also have consequences. I cannot see us surviving 2+ more years of this destruction without major declines that will take decades to fix.
