Reserved Classes In Trains Must Be Increased

There are two types of reserved classes in Indian trains under reservation category, mainly .One is AC and another is sleeper class. I think one more class must be introduced between AC and Sleeper Class, which should be slightly costlier than Sleeper Classes, specially for middle Class families, qualified people. Because I see in Sleeper Classes most of the Labor/workers reserve their seats .So it becomes very difficult for middle class families people to travel with workers/laborers who keep on going out side of the state to earn money or come back always from their. It is very difficult to accommodate the families of middle class within them and it looks awkward also and chances of theft pilferage of their goods are more. Also they need civilized people to travel with. If middle class families go to purchase tickets for AC Class it becomes too costly for them to accommodate their exposes within their earning. More over since the bogies of AC are less so it is very difficult to get reservation in AC Class.And every body do not like to travel in closed AC compartment due to medical problems . I surprised to note that, how much incompetent people/ministers are handling Railway Department that still they are unaware of the fact?
If I am right, then please share the above as much as you can so that it should reach in the ears of these worthless ministers.
