After viewing the proposed wall designs it is apparent most of these entries have never spent much time on the border. I grew up on the border and have ranched along the border. I have attached a design that is feasible, will create jobs and use existing production capacity.
Besides Sen Cruz's funding proposal to use El Chapo's assets I would suggest putting a 20% EXPORT TAX on US CURRENCY being wired "home" (to MX and beyond) by illegal aliens working and residing in USA. This will encourage these people to become legal and it is easy to manage because we electronically control the CHOKE point.
