I have never suggested taking away that freedom. To quote myself:
The lottery issue is like school choice, it's preselection masquerading as fairness.
If you apply for a lottery or exercise school choice, you are by definition an involved parent, and have the knowledge resources to know that such options are available and how to take advantage of them.
The children of parents with greater knowledge resources always do better, and the schools where the involved parents are always do better. Thus, once again, the lottery system "skims the cream off the top" which obviously diminishes the comprehensive schools that must take anyone assigned to them.
In my area, I watch the charter school kids compete against the kids in the comprehensive schools at sporting events. The differing income level and social status are obvious. The charter school field hockey players all have team jerseys and legwarmers and water bottles donated by parents. My kids team (they laughingly call themselves the "ghetto" team, because they have more non-white players than any other in the league) has jerseys that were paid for by tax dollars. So, who got more funding? Why, it was that ghetto school, the numbers don't lie.
Charter, magnet, and private schools, lotteries and school choice are all engines of selection, that make privileged people act to harm the less privileged. We need comprehensive public school nationwide, not funded by local taxation, and with mandatory attendance from all social classes and economic circumstances. It's our best chance for the best possible future for all our children. We can break the cycle, and lift the penalty for being black.
