The whole notion of any land claiming to be "the greatest country in the world' is absurd, borderline fascist.
But get rid of California? Any state the size of California will have a lot of good things. But take just the part of it where I live, the north, in an area roughly the size of North Carolina, we have one of the prettiest cities in the world, where so many people wish to live that property values make it difficult to do so. A city without the cultural riches of New York, but one that produced Bill Graham and the Fillmore auditorium, the Grateful Dead Jefferson Airplane, and which transformed the nation with aspects of the counter culture people now take for granted.
Look at the map and draw a line from Mendocino to Lake Tahoe south to Yosemite and west to Monterey. Though the beaches could be warmer, you have unparalleled scenery and coastline, the jewel that is Tahoe and the Sierra with great great skiing and fishing, the historic mining towns of the Mother Lode, the wine country which rivals that of France, the fascinating delta, the nations salad bowl in Salinas and the produce of the Central Valley, the creativity of Silicon Valley which has transformed America and the world, and two of the greatest universities in the world. From my modestly size home in Berkeley, I look out over the jewel that is the SF bay, the city that gives the bay its name, the coastal mountains of San Mateo County.
Top that, Texas.
