Air tickets for Singapore next year

We have to go Singapore next august for a big family event. Since I already know the dates, I thought I check out the air tickets. Yoo hoo! For a family of 2 adults, a 3 year old and a 2 year old kids, it would cost 18 719.48€ on economy class.

OK. I will come back and buy these tickets later. Not because by then I would have save enough to buy them. I just know that the price will drop as the dates get nearer.

Seriously, who would buy them at this price?
