China may get paid a cut of your hard earned dollars, but unless you're buying direct from Alibaba, you're usually also supporting American companies like the online HBS retailers, Amazon, or specialty brands like Anvil (part of Blichmann). Unless the global supply chain drastically changes, we're in this together.
This being said, given a viable and competitive American option, I'll choose it.
I'm no fan of China from a political perspective, but they did not manufacture the virus or unleash it purposefully on the world. They did initially act irresponsibly and were in denial, causing a delay in aggressively responding and effectively communicating... but look within our own borders and you'll see the same phenomenon.
I am very sorry to hear of your situation and sincerely wish your family well. It's a genuinely scary time for all of us (even those still in denial!).
