Even my maid and gardener have Android smartphones with internet access these days, so I don't buy that at all.
Artificially supporting a dying industry just to keep people employed may be good in the short-term but eventually the inevitable will happen sooner or later. Rather let it be sooner so people can reskill or retrain. The same thing happened with telegrams, steam engines, cotton mills, and a hundred different old technologies and industries. Progress marches on and people need to either adapt or die. The fact is that the postal industry is dying and obsolete. Many businesses have completely stopped using the postal service as technological alternatives have presented themselves. Revenues are drying up and there is nothing they can do to reverse it.
