While currently witnessin' a sort of discontinuity or rapid change in the economic base will a transformation of the superstructure follow on? Or are we only talkin' about a steady trend?

'Ya all kno' how culture, art, religion, political institutions - all the ideologies - are more resistant to change but according to Marx will be transformed. At least, that's what this simple blogger-mom read. Our traditional attitudes are supported but are also subverted by the economic sphere. What does it all mean?
Will it be a different story where, according to the rhetoric, there's only a middle class?

.....what we produce is always miles ahead of what we think......
another tenet:

Mankind always takes up only such problems as it can solve ....we will always find that the problem itself arises only when the material conditions for its solution already exist or are at least in the process of formation. Marx.
