• it maps (almost) 1 to 1 to machine code
• the primitive operations are very primitive
• the facilities for combining primitives are crude
• hence doing anything non-trivial takes lots of primitives
• not portable between architectures

are any of those relevent to your statement?

so...
just as assmbler "mismatches" objects

     so objects "mismatch" relations

so you are saying objects are too low a level of abstraction?
