What's preventing us from expanding our civilizations underground?

Why are we so bound to the surface?

    It takes time but we are getting there. If we keep all the aliens from crossing the borders, we won't have enough cheap labors to dig!

    We will, soon enough, but not on Earth. The interior of lava tubes, along with other subsurface cavities, could prove to be prime locations for future manned missions to Mars by providing shelter for habitats. These natural caverns have roofs estimated to be tens of meters thick which would provide protection from the extreme conditions that would be experienced on the surface. The habitat would be protected from solar radiation, micrometeorites, extreme temperature fluctuations (ambient temperature is believed to be stable in lava tubes), winds, and regolith dust storms which could pose a threat to human health and technology. These natural shelters would also reduce the landed payload mass for manned missions which would be economically advantageous.

    It is costly, for the most part.  Easy to excavate loose soil and sediments, although loose soil and sediment will fall back in if you don't make strong walls. Hard rock, though, is a completely different story.  Hard to get through, costs money, have to carry it off to somewhere, costing more money.

    Besides, people actually like to have windows to look out of even when trapped inside their man-caves.  Windowless rooms suck.

    Its a lot of digging

    That's the future. Travel right now is two dimensional except for things like tunnels and bridges. A thousand years in the future, I predict we will have underground hyperloops all around America. As for now, we are bound to the surface because it's cheaper to buy a plot of land and develop on it than dig further underground. Also, many places want to be seen.
