Buying shares in prefabricated wall companies would be excellent! This is a growing industry and if Donald keeps going down the path he is going will be huge! After the border he will build other walls. Walls can keep people out or can keep people in! It’s a trap either way. Look at history walls have never been a good situation. Thank You for the excellent dialog! Be sure to invest only after researching completely. Research the people behind the company and be sure they have the proper suppliers to support product demand. This is always the key to a successful operation. An operation that will flourish and surprise the test of time.
