COVID-19 = Tower of Babel?

I recently read a Blog post today that "COVID-19 heralds the end of Globalism" and I can't help but think there is a grain of truth to this.

Looking at this from the point of view of just diseases, a homogeneous society is the most susceptible to diseases since the disease finds it easy to jump from host to host.  (Read what has happened with bananas for a real-world example.)  In a heterogeneous society, diseases spread much slower, or even die out, as the disease runs its course and can't find another host to infect.

Globalism is the idea that we are one big, homogeneous family.  It's open borders and people moving from one place to another freely.

From a disease point of view, this is a really bad thing.  If people from a location where the disease is rampant - especially if the disease has a long incubation time - move en masse to another location, the disease spreads easily.

If the borders are closed, the disease can be stopped, or at least the spread slowed to keep it manageable.

Logically, this means that globalism is bad for pandemics (or diseases that have that potential).

Relating back to the Tower of Babel...  The story is basically saying the same thing: globalism is bad.

Remember, globalism isn't about "diversity".  It's about sameness.  It's not about living peacefully with your neighbor.  It's about making you and your neighbor the same.

True diversity, a heterogeneous society, is good.  In the short term, it's good to keep COVID-19 down and, hopefully, out.
