The Radzyner Rebbe wrote (some 120 years ago) something to the effect of saying that the mases don’t wear Techeiles because the gedolim don’t wear Techeiles and the gedolim don’t wear Techeiles because the masses don’t wear Techeiles. Interesting phenomenon if it’s true.
That doesn’t mean that it’s not a halachic justification anyway. Take a look at the Mesillas Yesharim in chasidus.
