There are only two groups when it comes to economic status: labor and the capital-owning class. Labor is anyone who derives their income from their labor and goes all the way from the janitor to doctors and professional athletes.
Th idea of the middle class was invented to sow division with the “lower classes”. I mean look at your comment. You assert the “middle class” is getting slammed with taxes. Some (not necessarily you) imply the lower classes are somehow getting a free ride or are lazy. This is the propaganda.
We live in the wealthiest nation on earth. People without housing or food security is completely unnecessary. Charging people $1000/month for insulin, without which they would die, is only that way for corporate profits. Think about that.
