If you see someone being presented as some sort of "voice" of the Catholic Church the first thing to remember is that nuns are required to take a vow of poverty while priests are not. Sure some monastic orders like the Franciscans might voluntarily take a vow of poverty but how likely do you think it is for a monk to study the newest proposed tax code? Or spew their opinion on social media or on TV?
Personally I've known too many priests who drive luxury cars. And yes this is coming from an ex-Catholic (not a "lapsed" Catholic that's just a "you'll be back" BS label probably thought up by a Jesuit). To me hypocrisy is one of the most cardinal sins of them all.
