Scaled prices
I believe a worker should be able to afford what he creates. A coffee shop worker should be able to afford the coffees sold there even if he only earns £8 an hour. A food delivery driver earns £2-£3 per delivery when delivering food. He should be able to afford delivery of takeaways.
I propose pricing be conditional on income levels. Have multiple brackets of pricing.
For people earning very little, less than £12,500, the prices are adjusted to be 27% of the full price, so a coffee costs them £1. This is so that they can afford the produce and they are paying only the cost to produce.
If you earn more than £12,500, the price scales up accordingly.

通常，企业希望尽可能多地向客户收费，因此，了解购买者的购买力是每家企业都积极寻求的知识。
同样，每个企业都试图以最低的价格获得最大的销售额。因此，当公司选择将其生产过剩的产品出口到收入较低的国家时，这种情况自然就已经发生了。
Usually, businesses want to charge the clients as much as possible, so, the knowledge of the buyer's purchasing power, is what every business is actively seeks to know.
Also, every business tries to maximize sales, even at a lower price. So, something like this already happens naturally, when companies choose to export the surplus of their production to countries with lower income levels.
