If this is your genuine belief then try this exercise: put yourself in the shoes of the shopkeeper who owned his own means of production directly and sold his wares to his immediate community before Big Tech. Would you rather have his job, or would you prefer to be working in an Amazon warehouse where you're obliged to relieve yourself in a bottle for want of toilets while being surveilled in a manner a Soviet political officer might consider excessive?
I'd rather not be an asshole shopkeeper. If I were, I'd try to be a punctual and good shopkeeper. But without market pressure why would I want to be? Maybe working conditions in Amazon warehouses are not so nice, but even if they slowed it down a bit, I'd still buy from them because my city doesn't have a given item. Pissing in bottles is what it is, if you think you can make a better business than Amazon than you can try to attract those workers.
From the buyer end, you do see the problem right? You can have a slower and more expensive business, how many buyers would want that? That in itself is a luxury only people with sufficient money can afford.
I am not opposed to welfare schemes which would therefore incentivize amazon to pay more than that or improve working conditions.
