This is the Republican congress were talking about as well. The we don't want to spend money on anything congress especially infrastructure. How he's going to get them to approve of a 8 to 12 billion dollar project is beyond me. And his jerk off fantasy of getting Mexico to pay for it? No, you know what? Build the wall using our taxes, do it so you can see how Mexico isn't going to pay for something they never wanted in the first place.
it was never about not spending money, it was about Obama. Many of the same people were in Congress during the Bush years, which took us from our greatest national surplus to our largest nation deficit (people like to conveniently ignore that the 2009 budget was Bush's, as the 2017 budget is Obama's). Obama cut that deficit by almost 2/3, but disregard that.
And the wall is so fucking stupid, it'll cost probably 20 Billion to built, it will need constant upkeep and repair (running the cost even higher), it's a giant fucking boondoggle with Mexico (who ranks third in the world in terms of buying American goods, behind Canada and the ENTIRE European FUCKING Union, thanks NAFTA!), and it's overall effect on immigration is still up for debate. In short, it's a stupid decision that could only have been made by a stupid idiot.
