If Parents Are Having Kids for Old-Age Support, You Need a Child Who Can Earn Big Money

If you're having children for retirement, what you need isn't just a kid—you need a kid who can make serious money.

Only by having kids who can earn big—like, say, a celebrity whose daily rate is measured in "爽" (sheer satisfaction)—can you possibly get material returns that exceed the cost of raising them within your lifetime.

Having more kids won't multiply your happiness—by three times or five times—but it will multiply your expenses by three or five.
