It's also down to the 'greed for gold' of building contractors, and councils giving them planning permission [via convenient 'backhanders'] to create more and more 'concrete jungles'... That unscrupulous practice should be stopped, with more of an emphasis placed on preserving nature and building houses in sympathy with the existing natural environment.
Unfortunately it's also the case that the demands of modern life make people predisposed to living in rather 'grey' urban sprawls, jammed together like sardines, or in some soulless, out of town modern housing complex, where every house is identical and simply looks like an architect's drawing superimposed onto a landscape, as opposed to something more 'real', which actually belongs there.
The goal appears to be to squeeze together as many such 'dwellings' as possible, like glorified dolls houses, on every square inch of land available, in order to maximise profit, as opposed to building properties with a little character and individuality [and incorporating in them a sense of space], and which promotes in those who occupy them a genuine sense of well-being and a feeling of LIVING, rather than merely existing... Unfortunately, 'plastic houses' breed 'plastic lives'.
Older properties, of a similar cost (or often less) in my experience tend to offer more, certainly in terms of the above, if you're willing to put in some effort to refurbish them, if necessary, and maintain them. However, too many folks now simply can't be arsed and would rather just walk into somewhere that's 'job done', even if it's about as stimulating to live there as the magnolia-painted walls it's adorned with
