Ok well not owning a $10 Target iron, but the norms are classist. Before electricity, clothes irons were just hot pieces of iron with a handle heated by a fire (later with a hole to put in hot bricks/etc to avoid soot on the flat face). Heavy and a huge pain in the ass. Servants would do it because no normal person would want to spend time ironing unless they were coerced. A lot of cleaning norms are this way: it used to be that only rich people could afford servants to handwash all their clothes after each wash, and then we invented labor aids (washing machines, clothes irons, etc) that ended up just increasing the amount of housework to be done, so that it'd take up the same amount of time.

I'm still ironing my flags though. It's not like they wrinkle once they're put up, it's a one-time thing
