I agree. Even for Americans with experiences learning foreign languages and adapting to different cultures, it is not easy living abroad.
This is anecdotal, but I am currently in Japan as a visiting researcher at a Japanese university during my summer break; I'm a tenure-track computer science instructor at a Silicon Valley community college. This is my 13th time in Japan and my second-longest stay. I love being in Japan and it's a mission of mine to have ties to Japan for the rest of my life.
I'm in my mid-thirties, single with no children, and I'm knowledgeable of Japanese culture (including the work culture; I've interned in Japan for eight months and I've worked for a Silicon Valley branch of a Japanese company for six years) and I have the ability to have basic conversations in Japanese (I'm still studying with an aim for fluency), and so if push came to shove and I found myself with a bleak future in America, I could move to Japan long-term and adapt. In fact, it's a dream of mine to own a home in Japan.
However, it will still be a sacrifice. I would need to find a job either as a researcher or as a software engineer; a pure teaching career at the university level in Japan would be difficult for me until I become fluent in Japanese. Lower salaries plus the weak yen means it will be tough for me to pay off my dollar-denominated debts, including my student loans. In addition, I would like to get married and start a family one day, and while I'm treated well in Japan, I'm concerned about the treatment my children would face here (I'm a black American); it's one thing being a researcher at a Japanese institution, it's another thing being a child, especially a child with African ancestry.
Then again, the situation in America is deteriorating, with academia and science being under attack by our administration with breathtaking speed, and with anti-minority racism and xenophobia becoming normalized again in everyday society. Even if the Democrats win the 2026 midterms and the 2028 presidential election, we still have a very large voter base who is completely on-board with MAGA. Barring a situation that leads to the complete repudiation of MAGA by the American public as a whole, MAGA is going to remain a force in politics for decades to come, which will be my entire working career, and there will probably be future MAGA presidents in the 2030s and 2040s. The idea of a liberal democratic republic with liberal institutions that respect diversity and have an international view is under attack in America, and if MAGA succeeds, life will be more difficult for academics and minorities in America. I just don't know if there are any countries out there that resemble this old vision of America; perhaps Canada and Australia are the closest things.
Job-wise, I'm at a community college where we are not as reliant on federal funding compared to research universities, but I'm monitoring the situation carefully, and I need to be prepared for a situation where circumstances force me into alternative employment, including moving abroad.
