I restore 60/70s muscle cars... a lot of the parts are made in China, copies of original parts. Not, not as good as the oem stuff, but they don't make it anymore. Like mentioned earlier in this post, there are tons of aftermarket parts for cars, I also agree, no reason to single out chainsaws. Unless they start making every part for every saw they ever made, then we need aftermarket parts. I'd rather have a saw with aftermarket parts that runs and I can use than one with broken/missing parts and not running any day of the week.
I brought OEM GM fenders for my camaro for $95 Rear quarter for $145
The fitted block 69 LT1 was < $500 (Hi-nickle w/11:1 TRW floating pins).
Had a friend at GM dealarship back then. But could have got knockoffs for less
I junkyard scrounged a lot of OEM parts.
When I think aftermarket back then it was all USA like Holley Crower TRW and Eldebrock......all gone now as far as made in America
