There are other ways to do national service.
Pick up litter and paint over graffiti are two for that can be done by anyone.
All of those could be part of a national service system that provides jobs, income, and preferential student loan forgiveness, home loan rates, etc. Not to the level of military veterans, but something to help lower income young people get a path upward in life. You could offer one tier of jobs at age 18-25 for HS/GED holders, and another tier at age 22-30 for BS/BA holders. You could offer them the option of serving 1 or 2 years at each tier, for a max service cap of 4 years to receive max benefits. Certain skilled jobs would require a 2 year commitment but would come with job training. Eligibility requires criminal background check and fingerprinting. Etc.
