Is it more important not to break precepts through proxy, or to not cause suffering to your family?

An important point I see is how one furthers death and lying. Through working, you are taxed, and taxes fund the breaking of the precepts. Taxes fund war and espionage, so killing and stealing are definitely two which you break just by earning income. If one abstains from paying taxes, then your wage will be held. So nothing is really achieved here, since you are just laying the karmic burden on another person, which is arguably worse. Also, just being a consumer, even if say you make less then the taxable amount in your country, then you still fund abusive working conditions and abusive companies and practices. You fund massive amounts of suffering, since the money you pay goes into the company and then into warfare/espionage funding through the company's taxes. So, to leave such a life would really upset my relatives. My question is, is it more important to not cause suffering to my mother and father, and am I just being over reactive about this issue? Because the way I see it, I am certainly breaking the precepts of killing and stealing through proxy, yet if I were to leave, I would cause a massive amount of suffering to some of the most important people in my life. Also it may cause people who know me to really disrespect Buddhism, thinking "oh what a lazy/crazy person". Yet I cannot help but feel that contributing to the death of millions of people is less compassionate. Any thoughts please! This is a difficult situation. I am practicing Mahayana and am currently adapting the Bodhisattva vows.
