With respect you're being pointlessly petty. The argument is not that Google should donate to starving people in countries in which it's not operative. The argument is that instead of further pampering it's extremely privileged workforce indirectly via reinvestment or directly via higher pay, it should contribute more back to the global society from which it profits by paying its taxes fairly.

How can you argue aginst this when Google workers are collectively amongst the best remunerated in the world, Google is notorious for massive-scale tax avoidance and hundreds of millions of men, women and children around the globe are dying because they lack basic resources for life: Food, water and healthcare.

Each to his or her own I guess.
