Policies are determined by vote or by leader, rather than by structural forces in the system, mostly economic.
IP law in it's current state doesn't exist because folks got voted in who care about IP law, or because the voters care about IP law, or because the voters like the IP laws we're moving towards. IP law in it's current state...just like all other laws (+/- 3%) exists because the already rich and powerful are able to push public policy by writing the details of the laws in their favor.
Who gets elected doesn't matter.
What voters you've got mostly doesn't matter.
The structure of the system matters...and the structure of the system benefits entrenched interests at the benefit of the populace. The solution has NOTHING to do with what groups you have, and NOTHING to do with what formal system of government you have. It has everything to do with (a) existing economic power, and (b) how much power the government has to shift economic power...and the economic power ALWAYS shifts to whatever extent the government has power to move it in the direction of the entrenched interests.
Aside: Occasionally, but not very often, violence can make a difference. Then the already rich make a deal with the violent, and the violent get some power at the expense of everyone else, while the rich keep all their power.
