[Iron Munro]

A real wall made of concrete and barbed wire works well, has no moving parts, incurs minimum maintenance costs and does not require constant monitoring with around the clock operators. But it has two drawbacks as far as the federal government is concerned:

1 - A real, physical fence will actually work. It will effectively slow down and/or stop illegal crossings

2 - A real fence doesn't cost enough and doesn't require multi-million dollar contracts to purchase expensive equipment from companies run by large financial contributors to politicians. And once a real fence is built there is no need for additional contracts for expensive upgrades, maintenance and repairs.

What good is an expensive government project if politicians and bureaucrats can't channel the money to their friends and financial backers? Politicians are less concerned about the effectiveness of a project than the size of the contracts and who gets them.
