I wouldn’t have a problem with a reduction in the stipend. I don’t want a stipend to be tied to the number, because that’s essentially population control. All the children should receive the same amount.
Yes, all children should receive the same amount: ZERO!
When Joe and Jane worker have a baby, they must live within their means - their current salaries.
Same with Joe and Jane deadbeat, who both receive X amount because they are "poor". Having a child should not raise their initial draw by one red cent. They should live within the means that Joe and Jane worker are providing for them.
