The greater their success the more addicted they become! In a recent interview one of Canada's most successful bank robbers (Fifth Estate) claimed it was a rush (addiction) virtually impossible to break! (After serving a long prison term, release, and several years of successful marriage he bungled a robbery of a Royal Bank in Victoria!)
IMHO, Bay St offers better cover (No guns, no security) with the end result for those involved much more profitable and seemingly much less detectable!
Or is it just a matter that, "Money talks and BS walks?"
