That setup is not 30k, I know because I'm a sim hobbyist. Maybe if it had a surround canopy or a motion chair, maybe, and it's just maybe, it will start approaching 10k. Most people consider motion to be secondary and unnecessary for commercial flight simulation, and people are increasingly preferring VR over modular panels. Sim still doesn't require uprooting your life to live in the middle of nowhere, switching careers, and going into debt to buy property and risk financial ruin with a fickle investment. It's ok, some people are fine flying sim because they never would get to fly an Airbus IRL and wouldn't want a job as a airline pilot to get to do it, they just want to play pretend, and that's fine.

That's not even counting the not small chunk of people who are actually commercial pilots who also build sim rigs in their homes.
