I would say there is nothing in this world that, through you not purchasing, or working for a specific company, or not eating meat for example, is going to stop or change how we currently function, and treat each other, or animals, etc. We have to change it at the systemic level - where through changing how we value money for example, we change how we use resources, how we treat animals, and what we spend our time on... because have a look, when money is the most valuable thing, we are willing to compromise and abuse life. So it's about changing the system to where money is no longer god, and rather LIFE in it's entirety is honored and thus cherished and no longer abused.
So one thing you can do is be aware of the products you buy... research the companies your dollars support, spend your money where you would like to support with your finances. In terms of work... I've heard many times that there can be no morality when working in the world system, because the abuse is rampant... and so it's rather to understand what is here (say the sale of fishhooks as perhaps providing a living for some fisherman) and to instead focus on your financial stability that will encourage your ability to move and function in this world. If we allowed morality to guide what we do for work, no one would work in the financial market, or the beauty industry, or even as a scientist doing test on animals. So rather than resisting what is here as our world system, understand it... how is it interconnected? And how can we change it into a system that is best for all.
So don't fight or fear your participation in this world, rather become aware of where your presence can have an influence... understand our world, don't judge it. Create financial stability without judging what you do to sustain it. Work with the current reality, become equal to it in understanding HOW it exists, and HOW we can re-align it to support all life.
