Question

My daughter asked me, based on the Talmud in Sanhedrin 19, that one who supports someone is considered as though he fathered him, and therefore all of Jacob’s sons are actually also called Joseph’s sons.
Does that mean that the secular person from Ramat HaSharon, who together with his wife pays an average of about 100,000 NIS in income tax every month, and they have 2 children at home, is actually the parent of me and my wife and our 10 children?
The idea is roughly this: each person costs the state on average about 4,500 NIS per month. Times 12 people, that’s more than 50,000 NIS a month. Of course, my wife and I have never paid income tax and probably never will merit to pay it [at most a little VAT—not on fruits and vegetables, which there isn’t, and not on coats and various tricks and allowances], so where does the state get the money to support me and feed these 12 mouths and provide healthcare, education, transportation, etc.? [Whether it funds us directly, or whether we help it under the rule of benefiting someone without their knowledge…]
Answer: from the secular person who works hard [does reserve duty] and earns well thanks to his efforts, and pays a fortune every month. In practice, in a direct way, he is the one financing these 12 mouths…
If so, seemingly this is literally as though he fathered them…
