There are certainly always important things going on at home (Earth). I am not suggesting that these will always be more important than manned space flight; I'm suggesting that they are more important at this time. Are you saying that prioritizing manned space flight, above all else, is always a good idea? If not, what priorities have you before manned spaceflight? What's the rush? Are you concerned with climate change? Is the answer to it to move on from Earth, instead of _first_ trying to nurse it back to health?
