Can afford to eat

Notice how, early in the series, the main cast is very skinny. By the end of the show's run, however, they all look like they have each put on considerable weight. Judging by their ages then, when the show was made, they came from a time where food was rationed due to war and preceding economic (butt-ugly) depression.
American financial and industrial stability had arguably reached its peak during the 1960s, a trend that had begun in the early 1940s. Also at this point in time saw the American middle class grow tremendously. Large chunks of the world, if not most of the world, were not only at a point of recovering from World War II or getting there, but were big buyer customer base for American commerce, the latter of which had been geographically isolated from the devastation of World War II.
It's just interesting to see these trends take form over the course of the Perry Mason TV series.
