It reinforces the idea that "westerners are rich". The Chinese people believe in giving only the best to their kids, cultivating their kids, etc. It's not uncommon to see kids in China taking piano lessons, art lessons, martial arts classes, after-school tutoring classes, swimming lessons, tennis lessons, etc. in addition, they have high tech toys (game consoles, computers...) and all these require a lot of money. To them, this is how a parent should be, unless the reason behind having kids is the extra pair of hands on the farm.
So, the more kids you have means the more money you have. And if the parents themselves are not rich, it only means that their government is rich, or else who's going to support and fund all these 'necessities'.
