chores and child abuse

Too many chores are child abuse and parents should be punished for it. I understand that some chores are needed to teach certain skills and build discipline. When I was 16 I was a straight A student and finished freshman year with a 4. 0 GPA and I worked 24-30 hours a week, And stayed after school for JROTC team practice. I continued to do the same thing all the way through sophomore year. My only issue during this period of my life was the amount of extra things I had to do. For example one day I came home from a rough shift at work at 8 pm and still had to put away dinner and do the dishes but also as soon as I walked through the living room to go to my room my step mom told me I have to shampoo the carpets. I do not understand why she couldn't do it because she has no job and her daughter sleeps most of the day but yet she wanted me to shampoo the carpets at 9 pm after I came home from work and cleaned her mess in the kitchen. Things like this happened quite often, I also had a chore list with difficult chores. My chore list looked like this Sunday- go to work 8am-4pm, Then cut the grass, Wash 3 dogs, Scrub the bath tub and hand scrub the bathroom floors, Pull everything off the kitchen counters and wipe them and sweep and hand scrub the kitchen floors, Dinner dishes. Monday- sweep and mop the kitchen and bathroom floors, Wipe the kitchen counters, Wipe the rest of the bathroom down, Go to work 4pm-8pm, Put dinner away and dinner dishes. Tuesday- stay after school for JROTC team practice until 4;30pm, And babysit my 3 sisters while doing chores sweep and mop the kitchen and bathroom floors, Wipe the kitchen counters, Wipe the rest of the bathroom down, Put dinner away and dinner dishes. Wednesday- stay after school for JROTC team practice until 4;30pm, And babysit my 3 sisters while doing chores. Sweep and mop the kitchen and bathroom floors, Wipe the kitchen counters, Wipe the rest of the bathroom down, Put dinner away and dinner dishes. Thursday- sweep and mop the kitchen and bathroom floors, Wipe the kitchen counters, Wipe the rest of the bathroom down, Go to work 4pm-8pm, Put dinner away and dinner dishes. Friday- sweep and mop the kitchen and bathroom floors, Wipe the kitchen counters, Wipe the rest of the bathroom down, Go to work 4pm-8pm, Put dinner away and dinner dishes. Saturday- work from 8am-4pm, Sweep and mop the kitchen and bathroom floors, Wipe the kitchen counters, Wipe the rest of the bathroom down, Put dinner away and dinner dishes, Shampoo the carpets, Wipe the walls and clean the dog cages. This was my schedule and they constantly added things to it and it got to the point to where I was too tired to keep up with it all and I had a mental break down. I never had time to my self and was never allowed to do anything, It was so bad they had cameras in the house that they could sit in their room or at work and talk from to make sure we were doing exactly what they want. If we did not do our chores the way they wanted even if it was clean we would be forced to re-do them and we had our cell phones and stuff taken away too and sometimes beaten. I have done some googling but I do not see anything that says this kind of stuff is illegal and it needs to be changed, Children and teenagers are not slaves and should be able to enjoy life at that age. Also when ai was working I was paying for the groceries too.
