i have also been to many diras and yeshivas.There are always some bad people everywhere.But the good that Eretz Yisroel does is much better than the bad you claim it does.Those people who usually do bad have parents that are to overprotective and so when they get a chance they bust out.Everything starts at home.Im here for 5 years and so far the worst thing i did was get drunk and sleep late.
Next….as to ur claim of kedusha..
Please go check wikipidea and type in Jerusalem Syndrome..it is a real thing..real syndrome..read it.Ive seen it happen.
You shouldnt be naive.U think ur kids will do better in America?
