Famine
And is the person who comes in and forces that person to share being any more moral? Come to think of it, on whose judgement can we say what food the person "needs"?
I wasn't judging moral implications - I was asking if that's what you said. Are you saying that every citizen of the US must pay for the choices of a half million people?
Someone in need who forces someone to share his wealth to keep him alive is more moral than someone denying someone the right to live, when having the ability to keep him alive. All I know is that if I have no other way to survive other than to be immoral, it is time for me to get immoral.
Since the USA is a democracy and the majority is for the way the tax system works, this means that every citizen should pay for the decission of those people to live there. Yes. I know you were waiting for me to say that so you can fire off an entire assault of counter arguments and bombard me with facts that would support your own opinion, but that is how I think, yes.
Why shouldn't people live there? When the structures which keep the land dry are being maintained properly this piece of land can be utilized for valuable means. It offers more value than it costs, otherwise I am sure that they wouldn't have built the levees to begin with.
90% of the Netherlands is below sea level, yet we can manage and offer a lot of value to the European Union, so why wouldn't this be possible in the USA?
... and since you edited your post I'll edit mine...
Of course a line has to be drawn, risk / cost assessment has to be made before deciding whether to build a town there. But in N.O. when properly maintained the benefits would outweigh the costs to keep the risk at a minimum. That's where the problem comes in. In the USA structures are being built to withstand events that happen once every 1,000 years. In the Netherlands the structures are built to withstand 10,000 years or more. Obviously this costs more, but when looking at the state N.O. is in right now, it is obvious that these costs do pay off. I don't hope we'll ever get to see a hurricane like that here, but with exception of a couple of villages I doubt many houses will get flooded.
