Deleted the comment to avoid offending people with that joke. But you can't compare developers with priests. I don't see being a priest as being a job, it is rather a life commitment to follow a certain path which includes "being poor". I was just joking because they never are, and in catholic countries like mine they often have a higher than average living standard.
A commitment to the Catholic priesthood is not a commitment to being poor. It is possible for a very wealthy man to become a priest while retaining his personal wealth, because the Church has no hard and fast rules on the subject.
Religious orders such as the Dominicans, Franciscans, and Benedictines, whose members are often (not always) priests make a vow of poverty. Ordinary diocesan priests do not.
Probably because Catholic priests are not universally required to take a Vow of Poverty. A notable group in the Church that does take the vow are Jesuits.
