Other goals, like money extortion, you mean?

No, they keep it in balance. And it would be a lie to say that SQL were any
declarative.

The reason why has nothing to do with imperative vs. declarative. It does
with the computational framework required to back the corresponding
paradigm. Compared to mainstream languages RA relies on extremely
constraining and extremely inefficient frameworks of RDBMS, even when
watered down with stored procedures. Nobody would seriously consider this
for universal purpose programming, except for pointy-haired academics.
