The US Federal Reserve (A PRIVATE COMPANY) will have 'unlimited QE'.
The US FED will print unlimited $s - AND - buy property with it!!!
Blades of Grass - is not a very good analogy because Blades of Grass are not infinite. There may be, many, many, but still not infinite.
The FED's infinite QE means there will be MORE US dollars than, Blades of Grass.
The analogy - the US 'currency' is not paper dollars - it is Blades of Grass. The FEDERAL RESERVE has ONE field and gives these Blades of Grass to the government and you work for them to buy your house, and food, and toys, ...
But now the FEDERAL RESERVE does not just have ONE field, it has EVERY FIELD on the whole world. Now it is cutting these Blades of Grass, buying all the, loans, bonds, etc. with them. So your $250,000 house (mortgage) The US Federal Reserve (A PRIVATE COMPANY) will own, for 250,000 Blades of Grass . So you will need to pay the FED the 250,000 Blades of Grass back: or they TAKE YOUR HOUSE!!!
But SOON you, and everyone else, will look out of their window and see that they have a lawn, with millions of Blades of Grass exactly the same.
Then you will realise that everyone has so many Blades of Grass, and WHO would sell a house for Blades of Grass???
TOO LATE, the FED has already bought your house using Blades of Grass.
You still have to PAY for the house, but the FED now change the currency to GOLD or SILVER (REAL MONEY). You have to pay for your house in SILVER: but you only have Blades of Grass, so has everyone else. Maybe your house will cost 500 oz ($7,310 on 29/3/2020) of SILVER, SILVER does not grow in a field, where do you get it - you have to work for it; how much SILVER will you get paid for your work??? Remember "A Dime a DAY"??? One tenth of an oz. So you would have to work 5,000 days to pay for your house now.
