I think that the 'by-products' of the Space Race are what really benefit us. The Race itself is pretty irrevelant. It forced both nations to push their technology to its limits and as a result of the huge government expenditures, we now have better technology to use in everyday life. Things like LCD screens, computers and energy saving and water filtration technology are all aspects of space research which is relevant to us.
