There is no real way to invest into Gaza's economy tho. It is under embargo, and everything that used to go in, went in through Israel. Israel checked everything for possible military applications. So no concrete, no wood. No plastics / 3d printing filament even. Want a new type of velcro, that has hook and loop on the same side, and sticks to itself? Apparently it's a weapon of mass destruction, since you can't get it in.
