The only thing those business practices and regulations reflect is that the 'entrepreneurs' get a lot of political and regulatory rights, and the people who work for them get very few.
That kind of arrangement works out very well for the former, but just because a king is doing well for himself doesn't mean that the serfs are 'positively culturally inclined towards autocracy.'

A country's regulations and politics aren't an average of its culture. They are an average of the culture of the politically powerful. All that you've demonstrated is that 'entrepreneurs' are a politically powerful group in America [1]. That says nothing about the average culture.
[1] Way less powerful than incumbents, but for some strange reason, it's not sexy to point at Comcast and Kaiser and Exxon-Mobil and Wells Fargo as examples of brilliant entrepreneurship.
Americans tend to be optimistic and positively inclined towards entrepreneurship. This is often refected in business practices and regulations.
