Let Americans waste their money. Yes, THEIR money. I can't believe they actually thought some other country is going to pay far that stupid wall. 
Let Trump spends his money on that wall. Such a crazy idea could arise only in his sick head.Funny part is that Trump says 'they're gonna pay for it eventually', which we all know is not gonna happen. In the end the US citizens will pay for the wall, if it will ever come that is. A lot of republicans aren't very keen on the idea as well
