Now you want to sleep.. need I continue?
In short, the violence is not in "letting someone starve". Most people aren't out there trying to starve themselves. The violence is in preventing someone from saving themselves. Being homeless/penniless is an eyesore for those that aren't. The actions taken to fix the eyesore are the source of violence. What happens to a panhandler if they refuse to comply with police's arbitrarily justified order to "relocate"?
The laws (and even the liberal ideology you adhere to) exist to favour the ruling class. Why would the ruling class do anything else? When the ruling class are the owners of capital, the laws and culture disfavour workers.
Ultimately it’s not worth discussing this to death yet again, it has been done countless times in the last couple hundred years.
The only real violence you mentioned is if police attack striking workers, which is exceedingly rare in most developed countries with the rule of law. What percentage of striking workers do you think are physically harmed by police in the us? If you think that is a likely or common outcome, we are probably living in different realities. You say that laws just favor the workers, but I wouldn't want to be a worker in a society without property rights. There is no point in working if any value you create can be stolen with impunity.
