Unfortunately, one can tell which kids were disciplined and which were not. Completely different mindset. Many women chose to have kids singly in my age group, combined with the psychobabble of no discipline and the party party party mindset. As a result a portion of Gen Y has no self-discipline, don’t respect the rights of others and since they’ve never been told no and had it meant when they actively rebelled, they are pretty messed up. Failures in life.
What irks me is when one of those who didn’t discipline their kids says “I didn’t spank, but my kids turned out ok” but it turns out their idea of OK is drug use, violence toward others and usually run-ins with the law. Sometimes jail time. How that is supposedly “OK” I do not know.
