>If genetic engineering and life extension become common place, especially if controlled by private companies which naturally seek profit above all else, who will benefit from them most? (hint: probably not people living on welfare)

Why not? People on welfare have access to better healthcare than the richest person on Earth did 50 years ago. They have access to pocket computers and communication systems far more powerful than the military could have afforded 50 years ago.

But this is beside the point. These ideas can and should be debated. Literally ostracizing people and thinking they are evil for having different opinions on them, is absurd.
