The EU, roughly, sees producers as a vehicle that exists to create jobs, and thus create prosperity for their employees.

Once basic life needs are met, optimizing for customers tends to only good for someone who is living off their savings/welfare/etc. Optimizing for employees is good if you, like the majority of the people on Earth, have to work for a living, or are supported by someone who has to work for a living.

Even in America, often producers wield more political power than consumers. Farm policies are often dictated by the interests of farmers more than the interests of people who eat food. Tariffs have traditionally been a mechanism to protect domestic producers at the expense of domestic consumers. Immigration provides economic benefits but some of these come at the expense of individual workers who face more competition. Even defense policy is affected: decisions are largely driven by the goal of creating or protecting jobs in particular states and districts rather than by the actual needs of the military.

Everybody eats food, pays taxes, pays tariffs, and benefits from the protection of the military, but 300 million people who pay marginally fewer taxes and tariffs, eat marginally cheaper food, and enjoy the defense of a marginally more effective and efficient military are often "outvoted" by geographic concentrations of tens of thousands of people who have substantial vested interests.

Given this inherent bias in democracy, I think it makes sense for policy to at least try to favor the consumer over the producer, just because producers do a good job taking care of themselves already.
