Automatically for ever uttering the 'privilege' phrase - which undermines anything else said, but not withstanding...
Its parents that decide to have children, and they evaluate their circumstances against the risks before having them. If there are any sacrifices to be made, it should be by those individual parents alone - its not up to any other member of society to support them in their choice of having children.
What you describe are the impacts that parents personally choose by having children. Clearly risks will crystalise for some and not for others, but ultimately each parent decided to take the risk and must live with both the joy, but also the consequences. Other parents will have made different choices when they felt their circumstances were right.
Your first 12 items are simply that some people earn less money than others - it's a personal choice about the circumstances in which to have children and of course circumstances may change, but it's their responsibility alone to resolve to meet their children's needs.
Given that elections take place at least every 5 years, you could never assume anything about schools being the same as when you decided to have children - it could be that every school place has to be paid for by parents, or that parents are mandated to help in schools 20% of the working week or every child gets an amazing school grant, or a pandemic causes schools to close or learning to move on-line, where parents must supply devices and internet - anything, it's still down to parents to manage the situation and ensure they provide for their children that they decided to have within the rules the rest of society makes.
If you choose to have children, you decide to take on the unconditional unlimited liability that comes with it - if you don't want that responsibility, don't have children. Others can choose to have sympathy, but also don't have to have sympathy - and either approach is fine; but nobody has to justify making a better life for their own family than others have done and choosing what is best for their family - "privileged" or not.
