First of all, you blame peoples' behavior without searching for incentives and shaping forces. This is very "kids these days" argumentation, and specifically blaming greed or an increase in greed is downright utopian. Past ages and societies were no less full of greed, nor can future ages and societies be cleansed of greed. However, unless artificially warped by an outside influence, most social interactions and relationships tend towards cooperation as the best solution (see the Prisoner's Dilemma). Competition is a great example of an emergent interaction which incentivizes "altruism": Forcing prices down, encouraging resource efficiency, punishing waste and fraud.

Second, your idea that our societies are suffering from deregulation is downright delusional. Artificially set interest rates and liquidity injections are the ultimate form of regulation, wherein governments actively decrease the entire population's time preference by inflating away their savings, impoverish everybody but the wealthy by boosting assets, and reduce competition by shoring up the biggest businesses to bloat up even bigger. Remove this ultimate regulation, and with the current conditions, markets would choose staggeringly high interest rates, forcing deflation and thus absolutely demolishing fast money, investment scamming, and real estate speculation overnight.

So no, my line of argumentation does not slide into yours. You actually don't know what you're talking about and rely on appeals to fantastical sentiment.
