Hello, voice of the devil's advocate speaking.
There's some good points being made here. One of the things I've noticed is that there has been a steady gentrification of the mix over the years. And I would ask players that, rather than focus on what you CAN have codedly and what you DO have codedly (Example: steaks and chocolate souffles and fine wines) that instead you focus on what the mix is supposed to represent. It's an absolute shit hole, a living hell, the worst possible place to live. Because, in my opinion, that's where one of the foundations of theme needs to be.
(Please bear in mind: these are personal opinions)
-You SHOULD be crying about the injustice and inequality of the divide PUBLICLY constantly.
-You SHOULD be doing everything in your power to schmooze and cater to corporates PRIVATELY in the hopes that someday you can 'make it' and get out of literal hell.
-You SHOULD be lying, cheating, stealing and fucking(over) your chums given the chance because it's one of the only 'reliable' ways to get ahead.
-You SHOULD be doing as much illegal shit as possible to make ends meet.
-You SHOULD be acting like every meal was the last because your rat warren hole in the wall is out of nutripaste and you don't have the chyen to buy another.
-You SHOULD be trying to jockey for power in your workplace, in the club, and on the rungs of the power ladder.
-You SHOULD be doing everything you can to make it just one more day under the oppressive crush of tyrannical powers that be, be they hypercorps, street gangs, the HOJ, criminal organizations or that asshole downstairs who keeps spying on you and ratting you out.
If you are getting into the headspace that your character is tangibly struggling to survive every single day in the mix I think you will find that quite a lot of other RP will quickly fall into alignment. I am fully cognizant that the mix is safer than ever, and that the mechanical reality is that it is easier to be successful in the mix than topside. That does NOT mean that it should be played as such.
Let me share with you an anecdote from when I first got playing, and I met up with an amazing roleplayer. I was someone who wanted to become a medic, but being new to the game, I had zero idea how to go about doing that. So I told my met-yesterday new ace chum 'I really need to find work as a medic.' My ace chum turns to me and whispers across the table: "I'm doing a job later, and I could use a set of eyes and hands to watch my back. No fighting, just as a medic." I immediately agreed. Said chum, a few hours later contacts my character and lays out the job: He's chasing a bounty, there's a chance that some people who are after him could find him on the job, and the bounty target was dangerous, to boot. But he could handle them. He needed to make sure he didn't bleed out on the job. Follow along and I'd make a couple thousand (Whoah, huge money for immy!?!)
So we went out, we patrolled all over the city, we ducked into some odd, off the grid areas I'd immediately forget about, and 40ish minutes later the hunt was called off.
Years later, I'd come to look back and realize the following:
-That was probably all the spare money that character, who was also fairly new, had.
-That character wasn't a bounty hunter.
-There was no mark.
-It was an amazing time that got me hooked on this game, and still talking about it some five, six years later.
-At no point were coded realities of the game involved, it was pure RP, and pure theme, and some chicken scratch for money. That's it.
Keeping that in mind:
-Yes you can casually stroll around the mix and the worst that you'll probably encounter on a day to day basis is a dip or a rent-seeking ganger begging for tolls. -Yes you have five star food that wasn't depreciated from your mix kitchen and you're not going hungry.
-Yes you can make stupidly huge wads of money doing basic as hell hustles in the mix.
Step away from coded reality and lean into the theme on an individual level. Some people will be block heads and say "Buh am richer than every corpie ah knarr!" Ignore them. Or better yet, decide that they, in their fame and wealth, need to be the first targets for venting the pressure from being crushed under boots all day, every day. For working endless hours on the assembly line to barely make enough for a beer and a cube, while this chum talks about eating caviar and having millions in the bank. Some people will get it, and will play along with you. Better yet, new players will get a feel for theme that 'feels' to be lacking and you'll have fostered someone who can pay it forwards later. You can be that nameless bounty hunter in a bar, bored and drinking beer who takes the initiative to do something themely. Or you can be one of the masses sitting in bars and bitching about how nothing is going on. Which do you prefer?
