Voting age at 18 is unconstitutional

I have to agree with Aggie Man here as well. If child labor law are followed to the letter, there are with the exception of a very few under 18 that would not qualify for a full tax refund when they file the following year.

Another thing to consider is that those under 18 that have not been legally emancipated would be ineligible to sign a binding contract of any kind such as a mortgage or car note. Technically, unless they committed fraud by lying about their age, a minor is not responsible for any debt ran up on a credit card that they have been issued.

It wasn't until fairly recently (past 20-25 years) that minors were required to have a Social Security number issued to them unless they had their name on a bank account set up by their parents or received survival benefits from Social Security. I had a friend in high school that didn't have one until his mother died when he was 17 back in 1987.

As for the push for 18 for legal voting age. The argument was that an 18 year old could marry, be drafted to war or drink beer at 18, but was unable to vote.

With all due respect to the OP, a better argument may be why do some jobs still require a minimum age well above 18, 21, 23 or 25 to be hired is not legally considered age discrimination? Some examples include truck driver, police officer, bartender, taxi driver, bank teller, fireman, paramedic/EMT and some elected or appointed positions of the public trust.
