Somebody will have to explain to me how that works because from my experience it works just the opposite.
In my experience most people are risk adverse; they would rather not take risk if they dont have to.
I see risk takers for the most part falling in to two categories; those who by their very nature take risk and those who feel they must take risk to escape their circumstances.
They entitlement programs essentially insulates the great multitude from falling in to the second category.
And actually entitlement program for all intents and purposes traps people in their lowly circumstances because being naturally risk adverse they will stay in the lower class because trying to rise out of the entitlement class entails risk of loosing those benefits.
There is a third category, those who put risk in the context of faith in a God who wants people to do some things that they cannot necessarily calculate the results of.
