Nothing quite says "rich children" like an indoor, child-sized train set that can move monied young lads around to their heart's content. Regular kids have to settle for tiny, toy train sets that they move around with their hands, but not rich kids! No, they get to ride their train sets.
Just look at this crazy hand-crank locomotive toy. For a cool $4,100 (plus $500 shipping), you get two trains and a 30-foot-diameter track to put them on. They can support kids who weigh up to 100 pounds, and they're propelled via hand cranks. And they'll make your kids obnoxious snobs. Just get them Legos like regular parents.
