A Heritage of Risk
As others, such as Zubrin, have pointed out elsewhere, we are the descendants of those who hazarded the unknown, who pioneered in the wilderness, who dared the risk to reap the reward - or, more often, to let their children reap the reward. By facing risk today, we can likewise hope to provide benefit to our descendants, including the benefit of a willingness to overcome fear. If we will not take risks, the fears that rule us will likely rule our children.
We have a heritage of risk, and profit from it, whether we dare to share in it or not, but by sharing in it, by the continuation of it, we stand to gain even greater profit, for us and for future generations.
