On the question of whether the federal government should spend money to augment physical barriers at the border with Mexico, I'm with President Donald Trump.
Yes, there are other, more important steps the government could take to control immigration. Many illegal immigrants came here legally and then stayed after their visas expired. Requiring employers to verify the legal status of new hires would deter them as well as illegal border-crossers. Trump has rarely focused on this issue and placed too much emphasis on "a wall."
On the other hand, Nancy Pelosi's contention that "a wall is an immorality" is absurd.
