Things that are seen and not seen-Catholic Schools

In Westchester, some Catholic school teachers are protesting their low wages. No one can argue that they get tend to get paid well, but some do (though it requires a Ph.D.).
I heard that they want an 11% wage increase. They were striking not too long ago, so it's obvious that they're trying to milk the Archdiocese for everything it can give and more.
What is seen are low wages. What is seen would be a revitalized staff. What is unseen are tuition increases (or using less quality material) and theft. Yes, these teachers who complain that they're not paid enough are stealing from every single parent. Subsitutes are brought in, school is closed, etc. They paid for their children's education. Isn't stealing the act of taking something, without permission, and without giving something in return? Parents payed for a full year of school, and they don't get it.
Not only are they stealing from parents, but they're stealing from the Archdiocese and anyone that contributes any money. Ultimately, these ravenous babies are stealing from the Catholic Church. And they say Capitalists worship the dollar? At least we're not stealing from the Church.
