Hmm... initially I thought I would go to Earth B, too. It would be nice to have a whole world to explore and live in. To finally be able to have my own island without having to pay an arm and a leg. To birth a new civilization with the benefit of the aggregate knowledge of thousands of years of human history.
Then I think about where I live now. Arizona was once such a place - inhabited, but with vast tracts of open land. Certainly a long ways away from a frontier state, but only a small percentage of the national population lived there. Scrub desert isn't the most beautiful landscape in the world, but the land was plentiful and it was cheap. In the last couple of decades, that has all changed. The developers came in. They built huge cookie-cutter developments -- mass produced houses essentially. They built schools, strip malls, parks. People want big houses for cheap, and so they flocked here by the hundreds of thousands. Phoenix became one of the largest cities in the nation. Basically suburbs sprung up all over the place. And until the sub-prime mortgage hit, it was happening all over the southern and western states in the US.
I could see that happening on Earth B. With no laws or regulations, I could see massive amounts of development extending from the portal. Developers would make a fortune and gain influence. Sure, people would fan out to build their homes out in the middle of nowhere. But eventually, they would be encroached upon and absorbed by big sprawling suburbs. With the technology we have, and the sheer mass of humanity seeking greener pastures, Earth B would quickly be tamed and settled. It might be exciting, turbulent, and violent for several years, but it would eventually become another boring place to live, perhaps more boring than Earth A.
No, as long as the portal to Earth B was open to anyone and everyone, I would not go. I'd rather stay and improve what we've got.
