Haimy, that thinking is very short term, if not harmful. Yes, some of the jobs you listed are being done by fellow yidden. But what happens when there’s no more room? The contractors/ builders/ utilities people start losing their jobs. The schools become extremely overcrowded, and children suffer from larger classes. Water supplies run low because the aquifer can’t support the thousands of new people that will either move in or be born in the next few generations. Cars are at a standstill, roadways are breaking down, and emergency personnel can’t handle the growth. On top of the water supplies, how else is the environment affected by the growth? Trees are gone, birds are gone, mosquitoes are running amok. Pollution is harming the air and water.
The only solution is to find a way to lower the cost of living without allowing such high density housing to continue unchecked. Unfortunately that will never happen in NJ. But BMG and Lakewood’s history was started by 15 students and grew to thousands of people. If there is a similar community in cheaper Penn, close enough to visit, quiet enough for growth, then many more could get a start.
