But that's self-evidently not the case. Formal and informal discrimination massively limit participation, and quite often commercial success is rooted in an ability to dump externalities rather than create value.
Sure, the US isn't fair. In practice it is grossly unfair. But talk to anyone with, eg, a congenital disability and it is apparent that this isn't because the US is doing something wrong, it is because life is unfair.
The US is very free. Some people have to work orders of magnitude harder to excercise their freedom, but in freedom of speech and action the US compares well with, eg, the UK, China, Russia, Middle Eastern countries, etc, etc. There are a few very small nations (eg, Luxembourg, Sweden, New Zealand, etc), where the numbers are smaller and the results are arguably better. But recall that human communities are governed by absolute numbers (see Dunbar's number) and reflect that the US does pretty well for its size.
Basically, don't conflate freedom and fairness. The US has a lot of freedom, but freedom is a pretty basic idea, and exercising it is crazy hard for some people.
The US has just as many (maybe more) laws and regulations as anywhere else.
Edit: upsetting individuals and companies may be a bad idea too.
Are you sure about that? Pretty certain I've seen articles covering similar stories up in Montana and like.

Here's at least one that was easy to find offhand: http://www.latimes.com/nation/la-na-montana-border-patrol-20...
re: this story, for example: nothing like this exists in states that are not on the southern border. From state to state there are huge differences in culture, demographics, and governance.
