The Walton family can't throw my in prison. In fact, they can't do much of anything to me besides perhaps denying me a Sam's Club membership.
Monarchy and wealthy families are not the same. Hyperboles like this don't serve your case.
If you believe in meritocracy and you pass your company on to your children who are not suited for the role, then they'll fail and lose it all, as is often the case.
In company towns the boss could absolutely have you thrown in jail if they felt like it. If Carnegie didn't like someone then the Pinkerton's would happily take care of them.
The only reason we haven't seen modern equivalents to the above scenarios is that the information age has increased competition. But if you already don't feel like you could sue any of the Walton's for any reason and win... then just wait for when their wealth is 10x larger.
They most certainly can. They simply have no reason or motivation to.
The Disney family can. [0]
