Childcare is expsneive period and it will still be if you force other people to pay it. I have never understood why people demand that society pays for their children. Having children is a 100% voluntary activity in todays day and age.
I don't demand that my hobbies get payed by society.
The taxes already massivly subsidies children by getting child money, paying for the whole school system and many other things as well.
I see zero reasons why one should just be able to have children and have child care and school payed for the first 20 years of your childs live.
