I used to say that too. But there's a catch. Our government sets economic policy. Economic policy governs citizens' ability to find and obtain work, ultimately their ability to prosper. If the economic policy is "anything goes" then we will see and have seen rise of economic machines that suppress freedom of expression in the service of increasing shareholder value. The questions I think we should be asking is "does this make sense?" and, "have the goals outlined in the constitution been effectively achieved?". If government has enacted policy that yields an environment where people are not actually free to express themselves, is this not a failure of government to secure those basic freedoms?
I'd be a lot more comfortable telling people not to bother with oppressive employers if, for example, we had a concept of UBI so that people could feasibly sustain themselves in absence of a private economic machine writing their paycheck.

In short, I am aware of the status quo but I think interpretation is ripe for a modern revamp given trends over the last decade.
