I am married and Catholic clergy. I have known or met several married Catholic priests. The Eastern Catholic churches have ordained married men to the priesthood for centuries. The real problem in the Latin Rite or Roman Catholic Church or Western Catholic church is that our people do not contribute enough to support married clergy. I have known deacons who were in full time ministry on parish the payroll. Most were underpaid when compared to protestant ministers with similar duties. I have met several deacons who, like myself, went into hospital chaplaincy as the only full time ministry that would pay a living wage. Of course they also had to provide hours of volunteer parish ministry as well.  I have a friend who is a Presbyterian pastor of a small congregation (couple of hundred families) he has a 6 figure salary and a large portion of it is not taxed because it is designated a housing allowance. 
Yes money is one issue that stands in the way of ordaining married men priests.
