Depends on the state. In some, even children under 18 can drink in a bar if their parents buy (I think Wisconsin).

And its not all the US at 21 to buy, in Puerto Rico you can buy alcohol at 18. Federally all those are legal at 18.

States that do not comply get 8% less transportation funding https://en.wikipedia.org/wiki/National_Minimum_Drinking_Age_.... Funding is obviously more important than those between the age of 18-20 being able to drink alcohol.

These same men (18-20) would be the first to drafted to go die for the politicians enabling these laws.
