Does it (1) go undone, (2) do those not on leave have to do it in addition to their normal work, (3) do companies set their staff sizes so that they have extra capacity to take up slack from those on leave, or (4) do they hire temp workers to fill in until the person on leave comes back?
That’s at least a much less serious limitation to job creation.
Especially "at least" 2 years. As in, 2 years was the minimum and maybe 5 would be better?
Therefore, it is more selfish to raise your child yourself than to have an expert to do it for you.
I shouldn't have to disclaim this by argument by saying that I'm not making a serious recommendation to anyone, but because parents are so defensive and irrational when it comes to how they raise their children, I feel that I must. I don't have kids and don't plan on having kids, so this is merely an intellectual exercise for me.
Choosing to procreate, period, is selfish. And yet we don't scorn people for taking that path.
