He doesn't care about them  yes. But does he need them? Yes because without them he is powerless. I feel you are not understanding Sauron. He is not a dumb heartless being but rather a smart heartless being. He realises that without his troops he is useless and he would send them to their deaths yes but would he send all of them to their deaths?

True the eastern kingdoms were huge but some did not have a huge devotion to Sauron as Rhudel and Near Haradrhim. When Sauron starts taking the population of people from kingdoms these less believing kingdoms will start believing less and less and join the Free easterlings.

Sauron is smart enough to know that he can't exhaust his troops. You seem to think that sauron would not care about using all his resources. Sauron does not care for his men's lives but he knows he needs them. You seem to think that sauron would lose nothing from exhausting his resources. He would lose everything from losing the support from the kingdoms. Because without them he cannot recruit more people to his side. Think about having the most powerful force on hand then using the populace as slaves, People will not follow someone who they know​ are enslaving them. People will not follow someone who they know is mistreating them.
