Not over the last few months, obviously. But in general I've never known a serious trader who didn't maintain a cash balance at some non-trivial level, if only to maintain liquidity for low-latency bets.

But regardless, the point was that all the "cash" you see in your investment accounts (even if you, personally, don't carry any) is predominantly treasuries and other short term high-confidence debt. Everyone owns treasuries, it's only true that very few people "buy" treasury notes.

I repeat: almost everyone has some kind of money market instrument, the cash balance of which is stored primarily in US treasuries (along with other short term debt). Almost everyone benefits, to the extent they have that asset, by interest payments from the US government.

If you want to make a point about wealth distribution, then make a point about wealth distribution. This was a subthread about government finance policy.
