Add in the effect of overly protective parenting and an emphasis on high self esteem that is not earned, and we get a lot of poor decision making (parents and children). Just to name a couple of things...
My older sister got in trouble with the law and our parents spent a fortune in legal fees to keep her out of jail. They sold their business to pay for this. Several years later the middle sister then stole $108,000 while our mother was ill.
I figure the stress killed the parents at 69 & 74.
Beware helping too much.
