What is the lower/middle/upper-middle/super-rich classes of Sirius?

[Emperor Tekagi]

A very good question. Considering in vanilla a million credits were a damn lot of money, while in Disco a single snub (no equipment, just ship) costs even more. You could just base calculations off one category you set yourself as basis.
If you take snub prices as "realistic" and 100% valid as basis, you would get to the result that everyone who's in the working class remains planetside or takes.. well shuttles to their workplace. And space travelling with their own vessel would start with middle class people.

But the high sums coming along with this, would raise questions about the prices of basic goods and houses. It's either questionable calculations based off ingame prices (why the hell would they use such an inflated currency though?) or basing it on what appears to be logic in regards of a char's job, family background etc. etc.
