At a point, this just goes to the competitive nature of our society. From a moral standpoint, if who we are is a product of our environment and our genetics, then we ourselves aren't anything that isn't predefined. Someone who is lazy is a product of their genes and environment in the same way that someone with a disease is the product of their environment and genes. So, what makes asthma (which I have) something that I'm applauded for overcoming with medicine while obesity is something people are generally frowned upon for overcoming with medicine? Well, the fact that we want to ascribe the later as a choice - the choice to eat.

Einstein didn't believe in free will. However, he said that holding people responsible for their actions was a pragmatic approach for society to take (presumably because such action changes the environment that we are all in).

There are huge struggles because people don't want to accept that they have less free will than they ascribe. As such, the goal is to hold people responsible for faults that you don't have and find excuses that let you off the hook for any faults that you have. There are organizations that create campaigns to get society to accept their fault as something that should be compensated for. Short attention span? That's ok because it's medical. Stupid? Lazy? Those are things that are the fault of the individual.

It's really hard. If you can medicalize your faults, you get legal protection for them. If you can't medicalize them, you're personally responsible for keeping them in control. That creates a huge incentive for medicalization of everything in the human condition. And we're all worried about being left behind in this Red Queen's Race.
