So the fifty year old that got picked up for weed in 1982 doesn't deserve to find anything more than the most menial job?
They said that it should be up to them, as to whether they hire that person after a background check eg reveals something.
There are very obvious cases where it makes a lot of sense to screen people based on background checks (eg a daycare or school). Further to that point, every business operator is different and has different beliefs. One operator might be ok with hiring a previously convicted rapist. The next business owner might be a woman who was raped in the past and has a very different view on that for good reason.
