People become violent when they no options for anything. The Syrian Civil War is a prefect example of this, in the lead up the civil war, there was economic polices that benefited a select few people, intense drought that drove food prices up for the common people, and a lack of way to show anger in a healthy democratic way (strikes, protests, etc.), lead to a lot of anger. The anger eventually exploded causing a civil war.
Right now, we all have a cost of living crisis ongoing, lack of political leadership to resolve these issues, and growing wealth inequality. The next global recession is going to have lot of angry people, who's only options are going to be die a slow death or do something and maybe die a slow death.
When it happens remember to direct your anger at the right groups of people, political leaders who championed the status quo for corporations and billionaires, talking heads who tell us to be "grateful", and corporations and billionaires focused on wealth hoarding. These people got us into this mess and will gladly leave all of us to sink if it means they get to keep their dirty hands on power.
