Hello, this is a problem i felt like its true. Since coming back from break i've noticed how bad the inflation is, seeing people sell cars worth 150k for 30k more frequently just cause they need vehicle slots for something else. Also noticed lack of motivation to do anything as quiet a large sum of people having not much to work towards. All those points you listed nice and here are some more that could possible help.
- Increase prices across the board. Houses and cars sure, but items that are recurring purchases are more impactful e.g. weapon imports, food/water, oil.
- Restructure and strengthen the tax system, also introduce a tax department maybe. Have it so that tax evasion is more of a necessity for criminals. I really think this is one of the more important things, any method that pushes people to spend instead of holding during increased prices is very important.
- Stock market trading. provides an opportunity for upside and downside. but important to keep cash moving around instead of being held.
- More controversial, degrading cars - a car would lose its performance over a long period of usage.
- Decrease wages.
I remember when i first joined the server back in 2019, where having 100k and a warrener was amazing for a new player.
But to be honest, new large money sinks is probably the best way. Also previous points are not fully thought through just ideas.
