Zdad,
You have no clue.
The catholic schools are supported by the diocese and they are controlled by the diocese. There is no endowment. Funds come from the investments that the church has (look at Trinity church, one of the biggest landlords in downtown Manhattan). They also collect from their members. Will you be willing to pay to a communal organization a tax on top of tuition? The schools charge tuition as well.
If a yeshiva would put aside for an endowment, I am sure that you would be questioning how they used that as well.
And are you setting aside the funds for that? I thought you were complaining about the people who give for plaques? All the endowments are named chairs.
While it would be nice to have an endowments, funding those is pushing off on to others. On top of that, these universities are still charging $50,000 a year tuition. Look at all your fellow OWS people complaining about that.
