We live in a globalised technocracy where people have been reduced to nothing more than economic units. Voting legitimises an illegitimate system. Don't go out to vote in their little charade. Have some dignity. Don't contribute to the tryanny of modern governance systems.
Your advice though might have been given in a good fate but many people will perceive it in different ways. On the election day if you do not go out to vote, you have given the manipulators the automatic ticket to do whatever they like at ease. Even when you know that the system is rigged and your vote might not count, but you voting will also make it more difficult for them to manipulate it easily. There is no other democratic way that is proven to bring in the people's choice apart from voting, and it is not nice to abandon it because the system is faulty. The best thing is to practice and keep devicing means to improve the system believing that one day it will happen. Don't go out to vote and the same people will recycle themselves in the system and make laws that will even make your home uncomfortable for you. Do not give up, give your all and work with like minds to make a difference.
You're against system where people is nothing more than economic units. That's ok. But also you shouldn't go to work, pay taxes, follow laws and etc. Because by doing that you legitimise that flawed system where people is just economic units.
Whether you're voting in elections or not, it doesn't changes anything in general.
Yea, OP forgot that be it as it may, he is a part of the ecosystem. No one can honestly work in isolation. So, bring ideas to make good laws in the society and not to chicken away.
