When parent take 10-20% cut of pay for my family to be more comfortable,
When gas station give you discount for filling two cars
When grocery store slashes prices for larger families,

Come back to me then and we will maybe discuss.

Parent would be horrified if after asking for discount, they had to pick which of their children get 20% less food, love, heat, clean sheets, clean facecloth, cuddles or attention yet giving that discount mean our whole family gets less of all these things.

Families might want a second car but if they can't afford it, most will stick with one. When families want a second child but can't afford it, they ask day care provider to cut fees AFTER child is born. No. Not okay.

No other self employed business person is made to close the doors to their business after 4-6 customers every day. Yet with income being capped by numbers, how can any parent think that asking for a discount "does not harm"?
