The reason why I like those articles are that they are compatible with my (very limited) experience with what I consider upper-class people. Of course I may be wrong, or me and the author can share the same bias, etc... I am just saying that there is more for me than merely interesting writing.

Taxing the middle class allows the government to get a lot of money easily: those are people who already have enough money that can be taken, but not enough money to defend themselves. From that angle, it is a good idea. On the other hand, the strategy of "taking money where taking money is easy" contributes to increasing the gap between the rich and the poor, and to elimination of the most productive part of the population, which some people would consider a bad idea. Unfortunately, the consequences of getting more tax money come quickly, and the consequences of destroying the middle class take more time.
