“Politicians are seen as untrustworthy and hypocritical. We talk a different language. We live in a different world. We seem to be scoring points, playing games and seeking personal advantage - while home-owners struggle to make ends meet and schoolchildren see years of hard work undermined by the stroke of a bureaucrat's pen.”

This actually first appears in Recent Experiments in Psychology (1950) by Leland Whitney Crafts, Théodore Christian Schneirla, and Elsa Elizabeth Robinson, where it is expressed:
: If we used a different vocabulary or if we spoke a different language, we would perceive a somewhat different world.
Randy Allen Harris, in Rhetoric and Incommensurability (2005), p. 35, and an endnote on p. 138 indicates the misattribution seems to have originated in a misreading of quotes in Patterns Of Discovery: An Inquiry Into The Conceptual Foundations of Science (1958) by Norwood Russell Hanson, where an actual quotation of WIttgenstein on p. 184 is followed by one from the book on psychology.

The Status Of Linguistics As A Science (1929), p. 69 <!-- 1958 edition -->
Context: Human beings do not live in the objective world alone, nor alone in the world of social activity as ordinarily understood, but are very much at the mercy of the particular language which has become the medium of expression for their society. It is quite an illusion to imagine that one adjusts to reality essentially without the use of language and that language is merely an incidental means of solving specific problems of communication or reflection. The fact of the matter is that the "real world" is to a large extent unconsciously built upon the language habits of the group. No two languages are ever sufficiently similar to be considered as representing the same social reality. The worlds in which different societies live are distinct worlds, not merely the same world with different labels attached … We see and hear and otherwise experience very largely as we do because the language habits of our community predispose certain choices of interpretation.

The Liberals' Mistake (1987)
Context: All of us are responding to the fact there is no system that can keep any promises. Everybody is fighting each other under the illusion that it is the "other people" that are causing the problem. We don't realize that we are all in the same boat. We are all suffering from the absence of a system that can pull us together and assure us that the results of each person's work will come back to him and enhance his life in some way.
Neither Democrats nor Republicans today offer any vision of how we can overcome our present difficulties and build a more satisfying life. Both offer merely palliatives and, at best, a holding pattern. We have to look beyond the politicians to see a different future.
