At the most basic level, the definitions are that the right wing wants to keep things as they are and the left wing wants to change them. There is one way to do the first, and innumerable to do the second. This probably accounts for a large part of the effect you observe.
(There are of course, many exceptions to the given definition; for example, conservatives wanting to eliminate government programs that are currently part of the status quo. But in this case, they are likely to frame this as a return to a previous state when they didn't exist, which is still a well-defined Schelling point. Right-wingers that do not fit this categorization, such as extreme libertarians calling for a minimal state that has never existed, are known to squabble among them as much as left-wingers.)
the right wing wants to keep things as they are
This is not actually accurate. On virtually any issue you can think of, the right-wing consensus supports changes in government policy. This is true to an extent such that some have argued that Republicans oppose everything about the liberal executive branch and civil service, simply because Obama is in office.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
