Software engineering is becoming more mainstream and so there is some natural title inflation that happens. I'd guess that some more obscure trade, say Bonsai tree making, probably has more normal and uninfected titles, but if it ever went corporate then someone with two years experience would suddenly be a journeyman or whatever.
