A strong border is important, yet the following issues (not in any particular order) are more important and urgent in my mind:
Clean Air, Water, and Food (and the gutting of the EPA)
Consumer protection laws
Infrastructure (Bridges, roads, hardening of tall structures)
Given these issues, money is better spent on the issues listed. A Wall will not keep the electricity on in the event of a EMP attack. Will not keep our air, water, and food safe to eat. If food becomes unsafe to eat, not having healthcare will result in wide range illnesses and chronic disease. Without our children learning the basics, how will we solve our basic problems? I am convinced that because of the greed and power hungry politicians, Soylent Green will be our only food source. Nope, the Wall Mexico was going to pay for is WAY down on my list of priorities.
