Stole fees ARE quite universal! Dioceses in some cases have substituted an "allowance" for the actual stole fee tendered, though this is not universal.  In any case, stole fees have long been considered priestly income and taxed by the IRS!  As for qualified musicians, I are one, and I have never gotten so much as a nickel (or a penny!) from a priest, or a Catholic pastor!    If you were to take a comprehensive look at the history of "stole fees," and the Catholic practice of Baptism, you might conclude that these are incompatible with the very nature of Baptism as enunciated here and elsewhere in the New Testament (such as Acts 8).
