The purpose of life is reproduction and having your own kids is the greatest joy in life. I am a very successful and wealthy entrepreneur who can do anything I wish with my time and I have done everything; travel, rock climbing, super cars, wine tasting, etc etc. Time with my kids is all that matters to me.

There's no "purpose" of life, it just happens, it's physics.

So now imagine you're not, and your life sucks because of such "successful and wealthy entrepreneurs" sucking all the wealth.
If your life is shit, you naturally don't want to make it even shittier just so you can produce people whose life will also be shit (thanks to the class society). Since we stopped forcing people to do this, they're naturally excercising their will.
But your wealth depends on them reproducing, so that's a nice middle finger they gave you by not doing so. You're concerned? You should be, that's the message.
