With all this war rhetoric thrown around, it seems a reasonable jump to declare essential workers troops on the frontline deserving of what we give other troops (free health care, pension, heavily subsidized secondary education)
Wait, like a real war? Who's talking about a war? Between what parties? I have heard nothing about a war, please explain.
That's not really right, because that implies that other people are using the word wrong. It's more that it's a word with a lot of uses, and you got stuck on one of them.
Merriam-Webster, definition 2:
2a: a state of hostility, conflict, or antagonism
b: a struggle or competition between opposing forces or for a
particular end
a class war
a war against disease
Note that last line. The use here is so extremely valid that it's an example in the dictionary!
