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.
If everyone is going to be paid fairly for their labor, plenty of electronics are going to dramatically rise in price, as they rely in materials that are often obtained through people working in miserable conditions, sometimes reaching extremes such as child slavery.
I for one am willing to pay more if that means we fight against the abuse generated by this system.
On the other hand producing a smaller variety of modular devices means you need less people overall supporting the same level of industry. Making designs open source and parts available means devices can be made to last longer than they previously did, requiring less manufacturing in the long-term. While I'm not sure where the equilibrium between this and other factors comes down, it ultimately leads to better working conditions and better devices so I'll take it.
