Children under the age of 16 should only be able to have 1 hour of screen time a day or 7 hours of screen time a week. This should be put in effect because children are spending to much time on there devices and barely socializing with people in the real world and aren't focusing on there studies. They would get more exercise and be much smarter if they went to the library and did research there instead of doing it on a device
This is a very good idea, except that it has several flaws. Who would enforce this limit? How do you account for online learning? What if the device is the child's only way to communicate with peers and parents who could help them with homework? I know that these are not the only things that students use their phones for, but all parameters and exceptions must be carefully thought out. Taking away devices will not necessarily increase productivity or increase fitness.
You would need to scan a card every time you use a device. If your card runs out for that day or week it is locked by pass code. Every parent or guardian has the passcode for the child to use if at school or if absolutely necessary. The passcode can be changed in case the child finds out the passcode when not intended. This is how it would work and to answer your question about emergency calls. If you are out of hours you have an emergency call to call 911. That is how it would work.
Even though you have explained the IDEAL system for this there are still major holes in the theory. The Government would control this? The government is for the people, not the other way around. If the government controls screen time,it is only a matter of time before the government has complete control of what appears on the screen. Who decides what is absolutely necessary? Who is to say when and where this scan card is used?This is an opinionated decision to be made by the parent or guardians
I'm only stating the facts and presenting the possible backlash. It is the people's right to decide how their children are raised and the privileges.That is all and best of luck during the voting period
