I think it'd be a morally-repugnant thing to NOT steal it.
With how much money is wasted by developed nations, let alone how much money is wasted by developing nations, even a small portion of your 40-60 million would easily save hundreds of thousands of lives or would, if spent wisely, help put an entire city or town in Africa or India into a state of near-self-sustainability. At the very least, it would buy a ton of condoms (and a ton of education) for the families in poor areas that find it to be a fantastic idea to have kids when you can't even feed yourself. And, for the developed world, I'd throw a few million that would save thousands of lives by paying for medical procedures and the like.
I'd still keep enough to keep me and my family sustained for life, sure, but the rest is going directly towards saving lives.
In conclusion, you either haven't thought about the consequences, or you're kind of an asshole, if you wouldn't steal the money. Sorry.
