LEGO Studs would be the most effective way of balancing our economy.  Not only would it provide more money circulating in society, it would also give children their own currency that will help show them the true value of money.  For this to work we would need to assign values to these studs.  The most basic coin would be the silver stud which is worth $10, then there would be the gold stud worth $100, then there would be the blue stud worth $1,000 and would make the silly noise when you pick it up, lastly there would be the purple stud worth $10,000 and would also make the funny noise.  Of course if you collect a certain amount of studs you would get the achievement True Citizen and would be rewarded with a gold brick trophy.  Different areas would require more or less studs based on the economic stability of said area.

It's a great idea except it's a horrible idea.
