This is something I think a lot of "do-gooders" miss. We're only in a position to do better because we took care of ourselves. It's a prerequisite. The flip side of that is taking do good (for the planet, for society e.g.) to an extreme where that becomes the only focus while letting everything else go south. We can take care of the planet only if we have the economical means to do so. We can help others only because we have enough to be able to do so. Environmentalism taken to the extreme says we should dismantle our economy because because it destroys the planet, however in the process of dismantling our economy we are taking away all the tools we have as well. If we're all poor the environment is going to do worse. People will go back to burning wood to keep themselves warm instead of e.g. using solar or nuclear power. We can have freedom only by having a culture and environment where that doesn't equate to chaos. Taken to an extreme "freedom" is chaos.

The other way of putting this is the well known saying: the road to hell is paved with good intentions.
