Was Dylan upper class?

The Klebolds were living in an -upper middle class to wealthy- neighborhood but struggling.

Like Eric’s family, both his parents worked.

The house they bought was a bit too much for their income within this upscale but rural neighborhood, and it needed quite a few renovations. From what Sue mentions, it sounds like Tom did most of the renovation projects.  They moved in in 1989 when Dylan was in the 3rd grade. The house has been a good investment property which easily increased in value in a desirable remote location. But Sue and Tom struggled a lot to keep that house, yet it gave the outward appearance that they were “upper middle class” or “rich” even.  I would expect Tom’s real estate business along with rental properties they owned helped to bring in extra passive income.  Again, I would put Dylan between the middle to upper middle class spectrum.  Their large house gives them the appearance of being an upscale middle class family but appearances can be deceiving.
