I agree that there is a part of entrepreneurship which include being able to understand the rules and laws and use them efficiently, but all these familiarities used to game the system are only valid if only a minority of the people use them. One people finding this trick is ok, but big companies being able to buy these tricks is another scale.
Maybe using these tricks was what actually enabled these "one people" to grow into big companies? I don't think it's as simple as "Small companies all pay their taxes, only big companies cheat because the system is unfair".
Imho there's plenty of opportunities to cheat without ever being discovered as a cheater, the vast majority of people simply don't notice them as such or when they do refuse to abuse them, out of a moral obligation to society.
That last part isn't the same for everybody. I dunno which election it was, but I think it was the GOP who ran on this whole "Maker" theme where they pretended people are all living in isolation and nobody uses public infrastructure for any of their success. That pretty much summed up the whole mindset behind "not paying taxes" pretty aptly.
