“Young Man, you are being sold a bill of goods”. That is, if you dutifully follow the rules as set down by the current establishment you are. There are lots of half-truths, distortions, falsehoods in what you are told. Most importantly, the decisions you make are affected by what you are told and the world view that arrises from it.
In my parents day, they followed a simple set of rules. Be honest, hardworking, loyal, thrifty and good things would come your way. It worked out very well for them. These days, the rules are more complex, and unfortunately the virtues that my parents exemplified are not so well rewarded. This is not to say that one should throw these virtues out the window, but one needs to be much more careful in applying them. For there are those who would exploit your virtues, and do so without a thought of guilt.
What should a young man do? He should watch the system, large and small, very closely. Consider carefully what is seen and heard. Is it all consistent? Does it make sense? Think. For men should build their own worldview, not have one handed to them.
Do this for the rest of your days.
