Trump's Great Wall

There is no need to build a wall. Just punish the employers who hire the illegals. When there is no job, they will not come. However, these are the jobs even the welfare recipients do not want. If they do not come, who are going to take up these jobs? When they build the wall with Mexico money, they give the money (or benefits) under the table to Mexico. Hence, everyone 'wins' except the tax payers.
