(1) Everything that we face/do/live with is the subject/result of a design choice but we take them as given (i.e. not conscious that they are in fact changeable) (much like the people living in those house prior to renovation.)
(2) Poor design is every where, and their impact range from slightly annoying to the very significant (institutionalized / lifelong practices - think of the US' Company Law vs Germany's Company Law).
(3) Good design is there but not enough people learn about/from them.
(4) Everyone should be schooled in the ideas & knowledge of design, to detect/highlight, stop & counter poor design with good design.
But all these are nothing new as I googled a bit and found the following paragraph from wikipedia, which i liked:
In "The Sciences of the Artificial" by polymath Herbert A. Simon, the author asserts design to be a meta-discipline of all professions. "Engineers are not the only professional designers. Everyone designs who devises courses of action aimed at changing existing situations into preferred ones. The intellectual activity that produces material artifacts is no different fundamentally from the one that prescribes remedies for a sick patient or the one that devises a new sales plan for a company or a social welfare policy for a state. Design, so construed, is the core of all professional training; it is the principal mark that distinguishes the professions from the sciences. Schools of engineering, as well as schools of architecture, business, education, law, and medicine, are all centrally concerned with the process of design."
