NYC toddlers go through the same thing, and I hear parents here complaining about getting their kids into a good kindergarten all the time. There is a funnel from the best kindergartens to the best private schools, to the Ivy League schools, to the top law firms and medical schools, and for some of very best schools, the rate of acceptance into Ivy League schools is so high that by getting your kid into the right kindergarten they are essentially set for life. It is absolute madness that an interview at the age of four could be so determinative of one's entire life. Yet another way that privilege tends to compound.
