We know why society is the way that it is and it is no secret.
In the 40's and 50's people were held responsible for their decisions and their actions.
In the 60's onward, the effort was to blame "society" for the criminal behavior and bad decisions that individuals made. Instead of laying the responsibility for their predicaments on the individual, it was blamed on the amorphous "society".
Thus, individual responsibility was not celebrated. Irresponsibility was celebrated. All sorts of rehab programs sprung up. All sorts of government aid sprung up to help the irresponsible.
What was the result?
Well, you tend to get more of what is incentivized. Thus more irresponsibility and more dependence on handouts.
