Female day care brats, who are usually named Tyler, Tayler, Madison, Foxworthy, or Sheboygan, learn to speak in a loud, whiney, nasal voice, and continue to do this throughout their lives. This is called "being assertive."
Male day care brats are discouraged from exhibiting masculine behavior, which is called aggressive. However, this behavior is expected of the females.
These ill-mannered, shallow, and self-centered people are taught to think in groups, rather than as individuals. The trend continues into the workplace, where bosses raised in Day Care Centers encourage group thinking and group solutions to problems. This, of course, discourages discoveries by independent thinkers, such as Newton, Einstein, and Szilard.
