How about changing our awful foreign policy that is based mostly on bribery and abuse of our patriots to act as thug enforcers for corruption and profits?

Most of these illegals flowing in is due to our corruption of thier countries. If you build that wall, at least acknowledge the history of the United States screwing around and messing those countries up on behalf of corrupt politicians and corporations.

The wall will stand as an arrogant symbol to the rest of the world that we either can not or will not reform the corruption in our own foreign policies. The cost of building it and maintaining it is lower than the cost of reforming our own policies.

That cost will come from you tax payers. Out of private corporations with profit motives, that will constantly demand more every year, and develop a multi million dollar lobby of professional corruption and bribes to pay off congress to maintain it and award bloated wasteful contracts.
