I would argue it does matter. Not to say that absolute position doesn't matter, it does, and probably even more so, but relative position has some very real effects.
The main one that jumps out for me is power, and influence. As an example, it doesn't really matter if I can donate $100 to the EFF instead of $50 when a billionaire can outspend me 1,000,000:1 without even flinching.
