&quot;Mostly only well-educated and well-off parents get their kids into these programs. That kind of sucks,&quot;<p>It&#x27;s really important not to let 201x social concerns get in the way of this stuff. The good stuff always <i>starts</i> out with the rich. Always. It is virtually structurally impossible for it to happen any other way. (Not <i>quite</i>, but very much the exception rather than the rule.) Rather than complaining that only the rich have the thing it is far more important to work out how to get it improved and shared more widely; complaining about the rich having the thing doesn&#x27;t help that and in the modern political environment runs the risk of strangling the improvement in the crib. It is <i>always</i> easier to bring &quot;equality&quot; by cutting off the top than bring up the bottom, and you have to be very wary of that, because people will propose that in various subtle ways if you fall for the &quot;class inequality&quot; memeset too hard.
