Clearly politicians look at the 18-20 year old group as politically weak. They are scapegoats. Teenagers are targeted as drug users but the largest group of users are middle-aged men. Middle-aged men though often own property and vote. You do not get what you deserve but what you fight for.
People respect strength and take advantage of weakness.
18-20 years olds need to reassertive themselves. Today that is possible. This is tantamount to the jim crow laws in the South in the old days. Animals herd because they know that there is strength in numbers. We are your voice.
