Late game economy

With the cash mechanic, I imagine after some time the majority of the player base (that sticks around for the medium to long term) will be net positive in cash during their playtime. Meaning players will have hundreds of thousands or millions of $ a lot of the time.

Is there any info on how the long term economy will be managed? Or still relatively unknown at this stage?

For example in tarkov people talk about liking the early game where most players are poor. The reception to late game is a bit more negative when many more players have high tier weapons, ammo and armour. Does anyone foresee the situation being similar in WD? With the ability to buy helis, tanks, etc, will this be exacerbated?

Full disclosure, I have not played the game yet.
