All else being equal, BA's and management are making higher level decisions which have more potential than developers to create stakeholder value. All else being equal, they are therefore worth more as measured by the potential return their work brings to stakeholders.
Unfortunately, those higher up in the decision tree aren't necessarily more competent than those lower down doing the actual work - often quite the opposite (maybe because these types of people are driven by different motivations). So the reverse situation can occur - developers can create a brilliant product which succeeds despite the best efforts of management.
I have a great deal of respect for genuinely good leadership, vision and management skills. Personally I find such things as quantum mechanics and reasoning about complex distributed systems far easier.
