The problem is, someone had to build that modem, and your clothes, and the solar power, and the generator, and write the books, and the people buying the surplus produce need to get money from somewhere.
Don't get me wrong, it's a great lifestyle, but it's not sustainable for an entire modern civilization. Specialization is needed for societies - some people to mine, some people to make weapons, some people to make tools, some people to care for the animals, some people to act as defenders. Cities are built in order to keep as many people with as many skills as close together as possible. They aren't inherently a Jewish creation, and they aren't inherently evil.
The problem with cities is that they are established for the sake of major corporations and businesses without any care for the welfare of the people living within. The only motivation behind a city is fabrication of materials, which puts the constant pursuit of money first and foremost. The maintenance required causes new jobs to emerge that have no real purpose, such as office workers, who are essentially glorified computers.
The environment of the city becomes rushed and frantic. People don't know each other. But humans are at their heart social beings, and being alone in a crowd is a psychological damaging effect. So people turn to drinking, smoking, gambling, whatever else might strike their need. The rush goes on beneath as well. The infrastructure of cities is very rarely handled well, as when money is the goal, the one trying to make it very rarely puts care into the future, or the ability of others to make that money. Look at the water infrastructure in LA to see that - in time, the whole place will be unsustainable, as they simply cannot replace the old with the new fast enough to outrun the push towards collapse.
In the end, what I believe it boils down to is two regulations that should be in place:
1) Areas which are designated as residential must have a limit on the maximum population. That is to say, housing may not exceed such a state within each square mile block that, should the proper rules be met in terms of maximum capacity per home, no more than 4000 persons should be allowed to live within that region. This is to include homes alone and not property; a home on three acres may have the space to have a hundred people in tents, but if the house alone can support only seven, that would be the count for that three acre block.
2) No building should be constructed above a maximum height of twenty stories in height, save for the purpose of creating state or national landmarks.
These rulings would ensure a greater spread. I predict they would also segregate cities more efficiently into districts with more specialized focuses.
Give me free control over moving national populations and reorganizing the structure of the States, and I could have even niggers living in harmony.
