I think its a broad issue that is engrained in the power structure corporates have in the political landscape in the US. If we been following the recent campaign trail (Hillary vs. Sanders) you would notice that Delegates and Super Delegates get to gravitate to Hillary in the primaries - which is the power establishment tends to support Hillary. Word is that the power establishment is strongly tied to corporate interests. The funding sources for political campaigns for these 2 candidates is something worth noting with what you have already raised, Ali. (with Hillary primarily being funded by corporations and Sanders from organizations such as human rights movements). We all understand how powerful tech corporations in the US are not only in the US but also in the global landscape.
Even Trump himself has boasted about the fact that he does not get sponsored by the elitist establishments (the corporations in the US), if Sanders is not being primarily funded by these corporate entities who else is Trump really talking about?
