National Socialism is the opposite of international finance capitalism, i.e. the opposite of globalization. Under National Socialism, engineers would not lose their jobs to outsourcing, and great industrial cities would not be disintegrating and turning back to farmland. There would be no such thing as Goldman Sachs, or the Federal Reserve, or big box stores full of merchandise from China. If China were National Socialist too, the Chinese economy would not depend on exports. Instead of a globalized economy, there would be independent national economies. International trade would still exist (you could still drive a Honda if that's what you want), but it would be a fraction of what it is now. The financial system would be simple and straightforward; there would be no such thing as "derivatives". The economy would be based on industry, not on finance, insurance, real estate, casinos, and prisons.
There would be no dumbing-down policy in the schools or anywhere else.
Instead of dying, the oceans would be flourishing. On land, desertification would be reversed. The "cancer industry" would not exist. The environmental and psychological causes of cancer would be addressed, and cancer would be rare. There would be no need to argue about how to pay for health care, because most people would normally stay healthy without "health care" as we know it today.
Under National Socialism, cities would not be full of drunks and homeless people. There would be no such thing as multiculturalism, or political correctness, or affirmative action. Schools would not teach kids to listen to hip-hop. First world countries would not turn themselves into third world countries. Just the opposite: National Socialism represents the gentrification of the world.
I did not know most of this until recently.
