Zuckerberg has no ethics and is just mad that apple's lack of ethics isn't working in his favor. A businessman with ethics has very little chance of dethroning an entrenched cartel within a corrupt industry. The hypothetical ethical business looking to outcompete their rivals may be the only one willing to set fair prices, but they also won't be able/willing to do what their competitors do. They won't exploit slaves/children/workers to make their products. They won't bribe governments to pass laws and regulations to keep out competition. They won't cut corners by using poisons in their products and manufacturing knowing it will harm their workers and consumers. They won't dump their waste into the ocean and pollute the environment. They won't collude to set prices, limit supply, or shut out anyone who doesn't play along.
The idea that you can defeat greedy corporations just by treating customers better is a fiction. There's always more money to be made by screwing over everyone at every opportunity, and there's no shortage of greedy people willing to do exactly that. It's why we need the kinds of laws, regulations, and enforcement that even the playing field and allow ethical companies to thrive.
You can't jump into the middle of a rigged game where the referees have been bought off and expect to win by following all of the rules. You have to stop the cheaters and the cheating first to even have a chance.
I've never owned a t-shirt that wasn't made by an unethical clothing industry which uses child slaves and abuses workers in sweatshops to produce hundreds of tons of clothing filled with plastics and poison every single year most of which will be burned or left to rot in a desert on the other side of the world from the retail shop that overpriced it when they sold it to me.
I have no idea what the fair market price of a t-shirt would be in a world where no one had to compete with the practices of the current industry. I do know that it'd be worth every penny. The price being paid now in environmental harm, inequality, and human suffering is way too high.
It’s not particularly hard to find clothes that are made ethically. I do it for most clothes I own. It’s even easier if (and more expensive) if you wear more traditional clothes (wool suits, coats, dress shoes, etc). You can avoid a lot of the abuses by buying things made in more developed countries (though obviously workers still won’t be paid terribly well, and the garment industry in the United States has some unpleasant corners). This tends to make clothes more expensive, especially as higher quality, more expensive inputs tend to be used too, but you can probably find a tee that isn’t particularly pricey.
I’m kinda surprised you never tried to do this considering how easy it is and how much your comments seem to suggest that you care. Possibly we’re talking past one another and you wouldn’t find any clothing companies that meet your ethical standards.
