The connection between "distribution of wealth" and the crash of 2008 and/or macroeconomic conditions is entirely subjective based upon one's own biases and beliefs. I do agree that it might be indicative of something else that could be a drag on the economy, like problems in the education system. The best ideas for solving those problems are a combination of ideas offered from both sides. I would say there is a higher concentration of good ideas on the Republican side then the Democrats, though.
But that too is a subjective opinion.
I guess I am just not one to buy into the "emense impact" of a slightly more progressive tax code under Clinton being the cause of the 1990's expansion versus the 2000's stagnation. Many other factors were at play to create the 1990's, most of which were far beyond the goverment's control.
What do you mean by "positive rights"?
