Should we solve our earthly problems first?

I don't agree with those demanding to solve our problems on Earth before exploring space. One can argue that the budgets used for that could have been used for other causes, but on the one hand the total amount used is still small as compared to the money necessary to even solve one of the most pressing issues, and on the other hand, in many cases, the investment in space exploration has brought forward technology that can be used to provide for earthly needs for much cheaper or better than before.

Space exploration is definitely more attractive for many scientists or young people thinking about taking science careers than many major causes of concern on Earth. This means that it is easier to attract people with creative minds and commitment to inventions to Space travel than to fighting famine. But, imagine somebody actually inventing the replicator, making it possible to have nutritious, delicious meals using whatever is available. This could solve the whole problem of famine. 

It is widely known that there are several inventions that were originally developed in the space race, but actually contributed to solving major societal or environmental issues, or simply making the life of people easier or  more comfortable. From different forms of insulation to solar panels, from artificial limbs that can operate to (for a bespectacled person a real miracle) scratch-free lenses.

Under normal circumstances, money for developing solutions for simple or more complex problems of everyday life is scarce, researchers often spend more time on writing applications for funding than or actual research. With enough funding available for various challenges around space travel, researchers have a peace of mind, they can focus on their real goal, and create solutions. What is more, solutions that work in the extreme circumstances of space may also work on Earth, and their mass production, having less extreme circumstances, might be cheap and efficient. But for that to become a reality, the funding for the extreme, space version is a pre-requisite.
