But that's where governments can come in, and implement things like basic worker rights.
As for countries themselves, we could argue that they also live in a context of all the other countries, but I would say that for the reasonably large ones it is the case their political will is roughly equivalent to the collective sum.
To this point maybe no more or less than the sum of its Named Officers' political wills.
This legal person is effectively controlled by a very small group of people, but it outlives them as these titles are replaced (new CEO, changing board). Everyone else contribute to its function, but not its interests. They are recruited to work for the entity through an uneven symbiotic relationship, where the entity covers the simple short-term needs of individuals.
It then uses it the power amassed to benefit itself, and those in control. Either by simply being large, or by trading the immense resources it can produce.
To the entity, the individual is no more important than a random cell in your body (left small toe fibroblast anyone?). And just like in your body, only a small number of cells get to drive the machine.
This is very different from a grouping of individuals, where individuals are merely cooperating towards a democratically elected goal.
Anyway, corporations, for-profit that is, are driven by one tenet & one tenet alone, which is their bottom-line. And they only answer to their ruling shareholders. Customers, employees, their own product, the USA govt, etc are all secondary.
That is not neccessarily bad (It would suck if the tax office would entirely redefine itself every couple year) but it is something to be aware of.
