A simple question without a simple answer , only a simpleton would expect a simple answer to such a complex problem.
I do know what the answer isn't , it isn't to consume more , more quickly and concentrate more of worlds wealth into the hands of fewer people.
"Who is a politician, now or in history who you admire or in your opinion has done a good job?"
Another complex loaded question and it means nothing without context.
A good job as a politician? A good job for the party? A goog job for your benefactors? A good job for the state? A good job for the country? A good job for the citizens? A good job for the world? A good job for the planet? A good job for humanity?
It all depends on what you rate as a good job.
I would say John Howard done well on the first three in general and badly on the rest and even failed on the first three in his last term.
I would say Kevin Rudd failed on the first three but had a go at the rest but you can't achieve much unless you have power its all a balancing act.
