question:  By all accounts, Martin should be grateful for the descendants,
context: No one, least of all Martin, could dispute that a man's life should be guarded by his kin—but by those who hadn't been born yet? Nobody in the neighborhood was surprised when Martin's mother disappeared and Ninian came to take care of him. "He's dissatisfied with the current social order and killing you is part of an elaborate plan he's formulated to change it. But Ninian didn't know that and she went into a real tizzy, babbling that Martin had been sick and would make up the work. Martin was told to call him Uncle Raymond. From time to time, there were other visitors—Uncles Ives and Bartholomew and Olaf, Aunts Ottillie and Grania and Lalage, and many more—all cousins to one another, he was told, all descendants of his. Though they were in the house with him, in their minds and in their talk they were living in another world—a world of warmth and peace and plenty where nobody worked, except in the government service or the essential professions. It was then that Martin began to realize that either the whole lot of them were insane, or what Ninian had told him at first was the truth. When Martin was sixteen, Raymond took him aside for the talk Ninian had promised five years before. And, on those worlds, it's far cheaper to use native labor than to ship out all that expensive machinery. I don't mean in the now for me, but the now for you," Martin explained laboriously. "I'm trying to talk to you as if you were an adult," Raymond said, "but if you will persist in these childish interruptions—" "I'm sorry," Martin said. But he wasn't, for by now he had little respect left for any of his descendants. Perhaps a great-grandfather is responsible for his great-grandchildren, but a great-grandchild can hardly be held accountable for his great-grandfather."
output:  but he is unappreciative of the lifestyle they bring to him because he would rather have things the way he was accustomed to.  He sees that even though his lifestyle was rudimentary in comparison, it was genuine.
options:  yet he resents them.  He rebels against the new way of life they try to petition upon him.  and he is.  He is appreciative of the fact that they want to make him an integral part of securing their future way of existence.  and he is.  They have introduced Martin to a much better lifestyle than he was accustomed to.  but he is unappreciative of the lifestyle they bring to him because he would rather have things the way he was accustomed to.  He sees that even though his lifestyle was rudimentary in comparison, it was genuine.
