Question

What are the arguments AGAINST raising the gambling age?

Answer 1

What are the arguments FOR raising the gambling age?

At 21, you should be an adult. You can drive, vote, drink, hold down a job, buy a home. You should be able to decide for yourself how to spend  your time and money.

Answer 2

Because their is absolutely no reason to.

Answer 3

Why should a person be able to die for their country (18 years old for the U.S. Military) but not be able to place a bet in a casino?  I think the drinking age is ridiculous based on this as well.  An 18-year old kid can go to Iraq and have his legs blown off but he can't come home and go to a bar, that is the definition of ridiculous.
