Yeah… the difference is that one (sparrows) was just a bad idea due to a total misunderstanding of the problem. The sparrows weren’t the pests, the bugs they eat were.

The other (one child) is a good idea that was poorly managed due to unexpected cultural mores. Even so it would still be effective once people are “incentivized” to give up on the foolishness of prioritizing one sex over the other.

The one child policy really gonna be up there with killing all the sparrows long term…

Except that killing the sparrows was a bad idea.
