Rob, a college senior was given $10,000 by an aunt. Before she died, she told Rob to put the money to work and leave it alone, so that some day he could
leave money to his heirs. Rob is pumped. He has two great ideas, both of which
he learned about on late-night TV. One is to buy foreclosure properties. The
other is to speculate in gold. The people on TV made a killing doing very little
work. Their DVD's will tell him all he needs to know. He asks you which sounds
better to you.
