If only there was reasonable competition, or basically anywhere else I could get certain things without paying a crap load for shipping small things. Even in large cities there just aren’t stores that sell certain things like electronics parts, high quality brand tools, etc. The big box stores just don’t carry a lot of stuff. Not to mention soaps that I use for sensitive skin which places like Walmart doesn’t carry, but the drug stores all got bought out and closed down and the few left now have mostly empty shelves, too. Without Amazon, I just can’t get a lot of things I need or want without traveling hundreds or thousands of miles, and I live in a major city.

PR alone accounts for over 3 million adults, or about 1% of the US population, with little to no representation, most of them citizens. Wyoming only has about 580,000 people, or about 0.17% of the population, but controls 2% of the Senate, 0.23% of the house, and 0.56% of the presidential election.
