best financial advice was my tale of two families.
My family: Four kids, lots of clothes, expensive food, eating out, expensive new cars every couple of years. Died just about penniless and my dad was an engineer via the WWII GI bill. High wage but lots of money on alcohol and both of them a three pack a day cigarette habit. Tons of toys under the Christmas tree, lots of new shoes, hairdressers etc. Died penniless except for some home equity.
DH family: His Mom and dad High school educated and straight to work and worked lower paying jobs. Modest auto- one car and they frequently walked to work. Gardened, never ate out and food from scratch. Rare to have new clothes-lots of hand me downs and only two kids. No alcohol, no cigarettes, much more modest Christmas.
They both did the best they could but DH family had a high net worth when they died due to better habits. Instead of advice they showed by the best teachers, example.
By the way, with the four of us two will never have a pot to P in unless there is a mortgage on it, the other two are modest. Of DH and his sib, they both do OK but she married a spender. It has been interesting to watch the development as we all reach our 50's and 60's.
