>my preference to have less misery in the world
Go ahead and quantify misery or happiness in an empirically meaningful way. You can't do it. Felicific calculus is a pipe dream.
Plus you're still skipping out on the whole "most foreign aid actually hurts the poor" thing. They don't need handouts; they need business opportunities. You want to help the Africans? Open businesses out there. Offer them jobs. Those jobs will suck at first, but after a couple generations of genuine economic growth, that region will be a relatively desirable place to live.
Or you could just keep dumping resources on their heads and preventing local industries from forming. Whatever.
>What's going to happen if we do immoral things?
Then you will be in conflict with your fellow man, and will be wasting resources and exposing people to un-needed risk and violence. That results in the destruction of wealth. There are very real pragmatic reasons for ethical behavior.
>Since when are invisible rights more important than human flourishing?
Those "invisible rights" are human flourishing. Prosperity is a product of freedom, not the other way around.
>There could be ways to do it where you require people to
The moment you have the authority to "require people to" do whatever, especially on a global scale, you are already an all-consuming tyranny, and that power will be captured by special interests and turned to corrupt ends. You cannot use the One Ring for good; it must be destroyed.
>Currently only 2% of US income is given as charity
First, government spending crowds out private spending. If there were less government welfare, people would contribute more of their assets to charitable donations.
Second, if people didn't have half or more of their money being taken away in taxes, that 2% would be a hell of a lot more money being given to charity anyway.
>So even if some of it is wasted
Like 80%? You do know that the US gov't wastes 80% of tax dollars, right? That means that the portion of your taxes that go to charitable giving are cut down to a fifth before they go to do any "good". And that figure isn't unusual among governments. You want to create a global government and expect it to somehow waste less? Fat chance.
