Petition why stop under 16s from becoming more responsible?

our e-petition is to get the jobs for teens rules to change as we are teens and have been working on our campagin in our citenzship gcse and we want to augue against people who say its not safe for under 16s to work and so on, so we are doing this because getting a job can help with most things for example, university and some teen have no money to live or get the chance of higher edication and we are strongly for this campaign and we hope you are please suport us and we know at the age of under 16 we can't do some jobs and working will teach teen of today some life skilled lessons and keep them off the streets so we hope to open this issue wider thank you for your time.
