Last time I checked even a relatively small 737 is ca. $100 million. You must be related to Bezos if you don't consider that expensive.

Compared to lives lost $100 is not expensive at all.

But sure, let's forget about morals for a second (lives lost and all that) and be very cold and cynical about the pricing. Still - reputational damage, political outcry, people suing the company/government for "failing to do even basic security checks like belts and shoes" - $100 million is nothing.
