As much as possible I chose to be a part of the solution rather than a part of the problem.
Most modern day problems are mainly systemic, which is why I ALSO end up involved in Politics in most countries I live in.
"Don't be part of the problem" isn't a solution for systemic problems, it's just living according to one's principles but won't actually shift the entire system in any meaningful way unless one is a billionaire or a famous personality.
