Edit: Jesus Christ, people. If you buy a $150 Thinkpad made by slave labor instead of a $1,200 MacBook made by slave labor, you're still supporting a capitalist economy based on slave labor. We all do. We have no choice. The number of smug liberals in the comments saying "well I buy a cheap used laptop" or "well I buy coffee beans and make my own coffee" are completely missing the fucking point.
Don't tell yourself your consumption is moral. All of us make unethical choices every day because there is no ethical consumption under capitalism. Accept your shame and guilt and let it drive you to do better.
The "have no choice" argument is extremely thin nowadays and letting it fly is just leaking ignorance or at times hipocricy. Anyone living in the first world has an option to help and just want to blame the elite that are the offender. The assailants that enjoy the disparity in the world obviously aren't going to do anything about it so it is just convenient whine
