I think your generalising a lot of issues. Like inequality is a huge field all in itself - some of them major issues, some of them becoming less so.

If overpopulation is the prime factor the solution is, rationally, easy. Expand outwards into the solar system/space. (assuming we are talking long term solutions).

Yes, generalising to the point that we see the very root all classes of problems. Inequality for example is vague and poorly defined as I said in beginning. Overpopulation is deceiving and looks very silly at the first glance but as deal with more data, it turns out to be a giant. Expanding to outer space is easily said than done even if we are talking long term, of course we can, if we last long enough without problems but one is ignoring so many minute details in such assumption. But I too hope for best, Companies like SpaceX and Virgin Galactic are already on ambitious projects. We must wait and see what will prove to be the optimal solution.
