You are correct in your assessment of one side of the equation, but the equation cannot balance unless the other side has equal distribution of function and magnitude. In other words, using the open borders argument only works if what we are discussing is the free market without any other variable. The problem is that we have an invasion of our Southern border by armed extremists underway, with no acknowledgement of such by our own government. Armed men, carrying loads of material for sale to financially support continued operations against the US People and Government is an invasion, an act of war. The invaders We the People are concerned with aren't the families traveling with children to find employment and a better life.
