I don't think "decent" is any more meaningful than "competitive". Based on my experience, "competitive" has proven to be sometimes way below market value, I don't see why "decent" would be any different.

Some companies have no clue what "competitive"/"decent" really is, some do but are just trying to find someone to milk for cheap.

'Decent' could have a connotation of 'good' (though that depends on the source, and the location targeted) - it's in my vernacular, but would agree, it can certainly be offputting, and a case of your second point - milking for cheap.

How might companies tackle the issues some have listed here of displaying salaries, while not deterring people (assuming they're being fair, not exploitative).
