NASA stopped refurbishing their SRBs because it costs more to do so. SpaceX is able to drastically lower it's launch costs because of the immense savings they can realize by a quick turnaround for reuse. That's the difference.

Russia has drastically lower launch costs than SpaceX. Justify it now.

Mind giving your source? I found 2.5k/kg for falcon 9 vs 5k/kg for soyuz. The shtil is as far as I can tell military surplus and is now retired, so it's costs aren't really reflective of long term usage.
