"After Van Dough discovers the vault isn't filled with diamonds, gold and money and asks Richard Rich Sr. why. Richard says "I'm sorry to disappoint you Lawrence, but thats not what we treasure", how come the gates to the mansion have dollar signs all over them, the mobile above baby Richies cot is solid gold with dollar bills and jewellery hanging from it, nearly everything is made of solid gold and the dog has dollar signs printed all over it. If he doessn't treasure gold, diamonds and money, how come its all over the house."

Those things are all over the house to represent the fact that to them, money and gold is disposable and merely an item of pleasure. They use gold in the way normal people use wallpaper, and diamonds in the way normal people use glass! But, what most of us keep locked away in safes and banks are expensive possessions. Their high-security vault stores what most of us place on display. They place the sentimental value of objects above their financial value, which is opposite to the way so many people live. That's the whole point of that.
