Actually, all of the conspiracy-theorists I know are all extremely left-leaning.
Actually, it depends.
The left-leaning ones talk about how the good government is being corrupted by evil businesses. The right-leaning ones talk about how the evil government is fighting good businesses.
You see it all makes sense if you add in well known problems like the revolving door  and regulatory capture .
In this case the evil/corrupt corporations (and their wealthy owners) take over the government (and vice-versa), and then fight the good business to help out their evil cronies.
Finally, the combination of these two work together to perform rootkits on democracy like the Citizens United ruling, and the TPP/TTIP/TISA, so they can corrupt and dominate other countries as well.
It works if you think of corruption like an infection.
