I do think we're becoming a nation of people without shame, honor or a sense of responsibility and it is hastening our downfall.
People decide what to do based on whether they will get caught and what will happen, not based on right or wrong. For them it's simply a cost-benefit analysis. Trade 5 years in jail for $500 million? Yeah, they'll take the chance especially when that's the worst-case scenario. Put assets into trusts and family members' names, and even if they get caught their family is still living like the upper crust. And when they get out, they can go on a lecture tour and start making six figures a year again just talking about their crimes.
When faced with the choice to do something to help others or just turn away, they choose "do nothing" rather than make the effort. People who do get caught doing something wrong are not ashamed about it, they utter a public apology and assume that squares everything. Their apology is really that they are sorry they got caught, not for what they did.
If these billion-dollar scammers thought their entire families would be treated with disrespect, stripped of everything they own in order to make amends, without the hope of serving time in a country-club prison and later ostracized for what they did, they would not be so brazen.
