< Since you're an apparent fan of 19th century employment law (see "Seven Day Workweek"), I'm guessing your problem with newspaper boys is that they're not out working in factories and coalmines... >
I'm not too concerned if it's 19th century or any other century, the Constitution came before the 19th century and it still needs to be protected today.
If a 13 year old kid can work 365 days a year, which is currently legal and commonplace, 30 year olds should have be able to work seven days a week also at ANY wage that they work out with their employer, the minimum wage needs to be removed also, adults need to have the constitutional rights returned to them in respect to what wages they want to form an agreement at.
I believe the OT rules apply to hours worked over 40 not days in a row.
