I went to Toys R Us recently to buy my son a Lego set for Hanukkah. Did you know a small box of Legos costs $60? Sixty bucks for 102 plastic blocks!
In fact, I learned, Lego sets can sell for thousands of dollars. And despite these prices, Lego has about 70 percent of the construction-toy market. Why? Why doesn't some competitor sell plastic blocks for less? Lego's patents expired a while ago. How hard could it be to make a cheap knockoff?
