I think that's a bit of an exaggeration, and as suchmoon says, if you have examples to the contrary then please do provide them.

There is a well known troll who has spent the best part of two years whining about the merit system and how there are hundreds of good posters who are not getting the merit they deserve. He was asked on multiple occasions to provide links to these great unmerited posts so us merit sources could give them the merit they deserved, but he was unable to ever provide a single example.

There is a thread started by Loyce here - [self-moderated] Report unmerited good posts to Merit Source - where you can leave links to good unmerited posts for merit sources to review. I would encourage you to use it if you find such posts.

I'm not saying all this to be deliberately antagonistic. It's just I spend a lot of time looking for and asking for links to all these great unmerited posters, and very rarely has anything been forthcoming. I'd be happy to be proved wrong though.
