Yes, basically this.

And when you have an industry surrounding it (specialised companies that do only this & fund lobbies) the system just becomes a perpetual business for the sake of it, can't get rid of it.

Like filling for taxes in USA (or did that just recertify change?).

Or private prisons.

Too much profit incentive & too many people involved to allow it to be dismantled once it became obvious the product doesn't work/it doesn't give any added value.
