American culture is still seen as something to emulate in many parts of the world. Hopefully less so after the next four years. We’ve had the same stupid tipping culture emerge here as well - seems like a sign that taxes aren’t high enough at the top end.
It’s not surprising that people don’t show up to vote if they don’t believe they have a voice. Provide proper representation for them rather than the slightly different shades of purple on offer now. Allow them to voice the nuance of their positions and you’d probably have Kamala as the president elect right now.
This is just the trolley problem - you’re trying to force them to pull a lever when many people feel that the only moral choice is not to.
Give them a way to participate and they’ll be able to weigh the options.
