So again, I ask……why is the Mexican govt not pulling for an expansive worker immigration program? Why are they making their people run across the border like rats, risking their lives to get across?

They are doing exactly that. Perhaps you missed this story from earlier this year.
Of course legalized immigrants would be more likely to have to pay taxes. It is easy for employers to cut costs by paying illegal immigrants under the table and in cash. So if they were all legalized, remittances back home might actually decrease due to the tax burden if employers were forced to stop this practice.
