Almost every American makes a choice not to have children in order to enjoy leisure, travel, and other luxuries. Almost every fertile American could have one, two or three children easily, and 5-6 if they really tried. You don't need a larger house, or even a larger car, you don't need to send all kids to college, etc. etc. </span><div style="font-family:arial,sans-serif;font-size:12.5714282989502px"><br></div><div style="font-family:arial,sans-serif;font-size:12.5714282989502px">Also, the success of a K strategy or the quality of offspring, is measured in the fitness of the offspring. Spending 500,000 on educating a childless PhD is not a K-selection, it's a mistake.</div><div style="font-family:arial,sans-serif;font-size:12.5714282989502px"><br></div><div style="font-family:arial,sans-serif;font-size:12.5714282989502px">I have only one child, and yes, I know I could afford at least 5 more.</div><div class="gmail_extra"><br><div class="gmail_quote">Rafał</div>
