In fact, lying on a job application can, in fact, be a crime! When you apply for a job and are going through all of that paperwork---you sign at the bottom, and in most cases, what you're signing is to affirm the truth of what you have stated. This is true on the applicant history, your tax info, references, and so on.
You don't sign documents for nothing, nor does that signature exist solely to get you through a process of paperwork. Depending on the job and position, the degree of legality can be serious---lie on an application for the military, government, or a security agency, and you could be in serious hot water (beyond just being embarrassed)
I understand the (albeit dramatic) point you are trying to make, but what you've asked for a is a statute of limitations, after which one's crimes can be ignored. As you said, the company will decide in this specific case if 30 years was enough or not, but in general, there is no consistent precedent for what you are asking for.
I am sure if someone steals candy from a store and 30 years pass, that odds are no one will care, but more serious wrongdoings can easily be relevant, even years later. This happens all the time---getting away with something doesn't make it OK or absolve you of it. People are brought to justice (or at least brought public if it is too late) all the time to answer for what they thought they got away with.
I'm not condoning harassment or hypocrisy, simply stating the facts---and you certainly do not have to like them, but civilization doesn't survive through corruption & lying. People certainly make mistakes and we are all aware of that fact all the time, but that simple fact doesn't make our mistakes OK. We're still responsible---you, me, everyone, and if we mess up big time, then it's on us to answer for what we've done.
For what it's worth, think how it'd be if you applied for a job and lost out to someone that lied their way through and got away with it. That's a lot of changed history that could affect the rest of your life. Maybe many other lives. It's far from negligible and you do yourself a great disservice by using semantics to throw away a very valid point.
