..you and Sarkozy are both right. I would only say that the problem is not totally that we have too many people. It is more that we have too many people who are either incapable or unwilling to do anything to pull their own weight. They are entitled to a gracious existence merely because they exist.
my father told me a story of a man who had been called to the draft board in WWII. He told them that he couldn't serve because he didn't have any arms. They told him they had a blind guy filling barrels with water, go tell him when they are full.
I said that so I can say this, "Everybody can do something".
Back when Carter was the prez there was a regulation setting the temperatures in govt office buildings. This was to save energy. Every govt office building I went in to working on phone systems, every single employee had a personal electric heater under their desk. Government employees know exactly what everyone else should sacrifice, but feel that complying with their own rules and regs is just too inconvenient.
The really big problem though is that any form of govt enforced birth control would be attacked by everyone from the pulpit of the churches to the ACLU. In short, it can't be fixed.
