Let children contribute to the family business

They say "the family that plays together stays together." The same can be said for the family that works together, where the children learn a respect for an honest day's work, teamwork and the value of a dollar. On farms and in many small businesses, children performing age-appropriate tasks can be a big help to their families.
Now there's talk of reintroducing the Children’s Act for Responsible Employment (HR3564) which, according to the National Council on Agricultural Employers, "constitutes a virtual ban on adolescent employment in agriculture."
Is there much difference in a child doing chores such as washing dishes, doing the laundry or vacuuming at home under his or her parents' supervision and setting or clearing tables in a family restaurant where both parents are working? Such children gradually learn the business they may someday own and are probably better off than if they sat at home alone playing video games until Mom and Dad get home.
Case in point, perhaps, is the Nuzzo family in Clinton, Conn., where it has been tradition since Grand Apizza opened in the 1950s that the family's kids help out on weekends. The 13-year-old helps make pizza (but doesn't put it in the oven) and makes change; his younger siblings help their mother seating customers and busing tables.  Tipped off that kids under age16 were working there, Connecticut's Department of Labor told the family it had to stop.
Is it wrong for a youngster to water thirsty plants? Or to pick flowers for bouquets to sell? Or to develop an interest in the family business?
Granted, children should be kept safe, but that doesn't mean they have to be excluded from the family's business.
