That's simple because, there isn't enough quality posts been created. You don't expect meriters to hand out merits to undeserving posts (in their opinion) just because we want more merits in circulation. The truth be told earning of merit isn't a problem for quality posters and for those who aren't recieving the merits, all they have to do is step up their game and engage more in quality contributions to receive the advantages associated with it, which getting merited is one of.
