I guess lots of people don’t have a choice. The local schools are just strict (or not) and they have no other option but to send their kids there. The state schools in my area admit kids based on how far they live from the school, so the only option if you do not like the local school and cannot afford private (and get your child a place - all our local private schools are selective) then you have to move. For most people that just is not feasible.
