What an odd question. Is this just the "and yet you participate in society" meme trying to act as insightful conversation, or did you have something to actually say?

The majority of people sacrifice nothing. They won't move to a 1000sq or less apartment but instead want their 2200sqft suburban house. They won't move the place where they can use public transportation, they just keep driving their car everywhere. They won't stop flying around the world on vacation. They won't give up upgrading their phone every year or stop owning tons of clothing. They won't change their diet to eat whatever is most environmentally friendly.

Instead, they just blame the electorate. The electorate just responds to demand. Same as industry. Stop buying beef there will be no beef industry. Stop buying cars there will be no car industry. Stop buying things from the other side of the world there will be no shipping industry.

People keep expecting politicians to somehow magically do something but are usually unwilling to do anything more than separate their trash or once in a while, bring a bag to the grocery store they just drove too.

Yea, all of that is hard. But if you're not willing to do it, what makes you think the electorate could possibly pass anything no of their constituents is willing to do?
