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.
Seeing so many responses like this to the edit makes me happy. This is the intellectually consistent position imo: if you're going to take the position that "this is the world we live in" (which is valid) then you must also accept that there are degrees of consumption and actively choosing one of the worst ones without a strong rationale is less moral.
