It's not always easy living a more ethical lifestyle, and of course there's no truly ethical consumption under capitalism, but you can try.
Most people have too many things and in order to afford them all they need them to be cheaper. You need less than you think, you don't need the new phone every other year, or a new laptop every update cycle, or iPods or an iPad. You don't need a smart watch or wireless earphones or designer clothes or 5 pairs of shoes. You don't need multiple TVs or multiple games consoles.
Less consumption means more money for the things you need, which means you can be more ethical with your choices.
Of course if you're in a position of struggling to feed your kids, you gotta do what you gotta do. Too late to do anything about it at that point
