I would argue that not building retail locations is simply smart, not an unfair advantage.

The tax one is a better point. However, technically speaking, the burden of paying the tax falls onto the buyer. You are supposed to file any tax savings you get from not paying sales tax and forward it to the state.

Technically speaking, Amazon has done nothing illegal. It's customers have.

As for job loss, yeah, that's a whole other problem.

Thanks for your points.
