Sure, but your choices are to:
1. Participate in the system 2. Violently overthrow the system 3. Do nothing
Sitting on the internet and whinging about how the deck is stacked against you is choosing option 3.
Fact of the matter is that a lot of people picked option 3 because of whatever reasons they had and now a bunch of oligarchs and criminals are running the joint now.
Voting is the least you can do if actually running for an elected position is not an option.
What do you propose as an actual alternative?
