One of the benefits of this forum, for me, is that there is quite a wide variety of members with different lifestyles and income levels. Not all of the conversations directly apply to me and that's OK, as I don't have to read them. Alternatively, I can read them, even though they don't apply to me because, well, it's interesting to learn about other people. There's a definite advantage to rubbing shoulders with all types. Much of the advice and information here applies to folk at many different income and asset levels.
I suspect that if you sit down for an hour or so every day and read as many threads in this forum as you can, you'll find much that applies to your situation.
Socially, I'm probably middle class. However, financially, I think my material quality of life falls below that which is normally considered middle class. I live in a HCOL area in a small rented studio (285 sq ft) with my cat, and ride a bicycle for daily transport. For several years, I happily lived on $18K/yr. Then I bought a campervan, and upped my income to just under $28K/yr. I don't think that counts as a typical middle-class lifestyle, but don't you even
dare think of me as low class
