fwiw, i would support deficit
spending for infrastructure projects. if they're going to build it, i'd
prefer they build it with public funds than private funds.
so, not only is that not why
they're not building it, but it's also not a reason i'd oppose it. it's
actually a reason i'd support it; if you ignore the context of the

the reason they're not building
it is that it would cut off the flow of cheap migrant labour, which
would be disastrous for the surrounding agricultural industries.
the banks that control donald trump don't want a wall. they want a

allow across.
there are just a lot of very stupid people out there that fell for a lot of very obviously contrived nonsense.
