I am apparently not the only one who's ever been confused about this. Meta sites do not have an edit queue, and so the "edit" link is not active for (other users') questions and answers on [meta] for those with less than some threshold rep (1k or 2k depending on the site). The only reason seems to be that it isn't necessary and/or it's harmful to add another queue for mods.
The help section says that any user should be able to suggest edits, which is true on the [main] site. But because there's no suggested-edit queue it seems that the edit ability on [meta] only for higher-rep users (1000+; 2000+ on "mature" sites), which is the trusted-user rep threshold at which point you can make edits directly (without going into a suggestion-queue). I suppose this means that at 1k rep you can also edit meta directly, but it's a little awkward to suggest stuff that ought to be changed "out of band". This discourages editing on [meta], which may be a fine thing, but I think it also reduces participation, which is probably not a good thing.
There's an apparently-stalled (years-old) feature request to expand edit features in [meta]s. Does anyone else want this? Mods / high-rep users, do you not want this? Is this reasonable for beta-sites, like this one (as of this writing)?
I suspect this too much of an uphill battle, with losing cost-benefit, of marginal value.
