If you don't protect your workers or employees in your company, it will be difficult for the company to be productive in the community because the employees need to be in safe place or position, where they can be productive for the company to achieve income. This is the reason why people use to call on government to solve the insecurity challenge in the community, because they know that they can not be productive in the community if the insecurity continue, and the government must respond to them in a positive way, You can also use high salary to protect your workers or employees because the high salary will make them to be productive for the company to achieve their goal.
It's definitely not the responsibility of the rich to protect the working class people you know why cause everyone is fighting for their own growth and thus what the rich do is ease the effectiveness by employing the working class and middle set of people to work under them so they can be able to meet up their demands.
But it's the duties if the government to protect the lives of every individuals but this era it's not possible cause of selfish gains and quest of power, but a rich Man can as well protect the lives of his subordinate based on the fact that such person's have served and proven humility to him/ her so the rich can do that out of generosity and Love.
