It is great that privately funded organizations like yours do such useful work and help to define policy on matters of early childhood development. In your case the “legwork” is paid for up front for the most part but I think the point of the OP was that once that research is made law, citizens shouldn’t have to pay to know what the law is.
As to your bosses refrain it may be true in your case and many others. But there are plenty of situations where the reverse is true, that public money does the experimentation and private money reaps the benefits. A couple examples would be ARPANET or NASA.
