The little plastic operating lever on the toilet tank has a left-hand
thread. I cannot think of any good reason for this.

And in passing, the place where I got the replacement had three types that
would fit:

4" plain white plastic - $5.99
4" chromed plastic - $5.09
4/6/8" chromed plastic (cut to fit) - $4.29

Pay more, get less, I suppose....

Normally a design incorporates LH threads where normal use would loosen
RH threads. For example if a lever were mounted on the top left of a
toilet tank such that the lever were to the left of the mounting screw,
operating the lever normally would tend to unscrew it. Since most toilets
I'm familiar with have flush handles like this, perhaps that is the reason.

Yep. If you think about it, pushing down the lever has to work
against the force of lifting the valve off the seat - by pulling on
the chain.

So the plastic bushing that fits in the hole in the tank is trying
to turn left at every flush.

Old dodges(69 dart) had the same thing on lug nuts on one side of the car.
They tighten in use.

I just replaced the handle on one of my toilets and it was apparent to me
why the thing had a left hand thread. Does this mean I have a future in the
plumbing arts?

This topic is a sore point with me. Somewhere in my shop is the worlds
largest collection of left handed weed eater bolts. Every time I need to
change from the string head to a brush blade I have to go buy another bolt.
