The reasoning is that you were raised by somebody but when it is your turn you are avoiding the responsibility. If everybody start to think this way the human race will stop existing.
You can't renege on a "responsibility" you didn't sign up for. Furthermore, if someone asked me to make a list of mammals least in danger of extinction, humanity would be at the very top. The idea that we need to keep exponentially growing or face extinction strikes me as remarkably similar to pyramid-scheme thinking.
