Self-Evident
If you attempt to explain why you should vote to help others while exempting morality and selflessness (which can quickly veer into the tautological) from your argument, you’d be left with an argument from selfishness:
Why are you “owed” a police force, why are you owed a fire department, why are you owed clean water or electricity, why are you owed laws that protect your ideas through patents or copyrights, why are you owed anything you enjoy through a civil society that makes your life demonstrably better than a libertarian wet dream like Zimbabwe?
I’ll tell you why. Because as a civil society we’ve decided what’s a part of the commons, that which we can not individually afford but whose existence we recognize, serves us all. I have news for you: my life is better and more secure if you and your kids aren’t bankrupted by medical bills. My life is better if everyone has safe streets and food. My life is better when the next generation is well-educated to continue the prosperity of this great nation. No one is owed, but it is a gift we give to each other as citizens and the price we pay to enjoy the blessings of our forefathers. And it is the height of hubris to presume to take that gift of a civic society and act as if it never existed before you showed up.
I’ve no idea who wrote that, it is from some screenshot someone took and then posted to Twitter.
