And why is this a problem? If the government is willing to pay able-bodied people to sit and study religion, why should you have any qualms with it (as long as it is done legally?)
This is the united States not Israel. There is no Stipend for Kollel in Lakewood from the US Government.
People do things that might be legal, but are sketchy and do leave a bad taste in peoples mouths. Like In-laws buying a house and then renting to children and the government pays the rent to the parents via section 8. This might be legal, but its not something people would like.
Or people simply getting paid off the books so they are eligible for more government subisidies
