You can earn yield in gold under a gold standard, though it depends on how the financial system is structured.

1. **Bank Deposits and Loans:** People could deposit gold or currency backed by gold in banks. The banks would lend out that gold at interest and, in turn, pay depositors a portion of the interest earned.
   
2. **Gold-denominated Bonds:** Governments and companies could issue bonds denominated in gold, paying interest to investors who lent them gold.

3. **Gold Leasing:** Large holders of gold, such as central banks, sometimes lent gold to other institutions or countries, earning interest (a practice known as gold leasing).

While gold itself doesn’t generate yield, financial instruments tied to gold, such as loans or bonds, allow yield generation, similar to modern financial systems.

Just substitute gold with bitcoin 

 That's the description of a scenario that destroyed the gold standard, hope it never happens to bitcoin

 We're not there yet, but maybe in the future, we will have verifiable full-reserve Bitcoin banks. 

 Or banks will be where they belong, in the history museum. 

 So in your communist world, nobody can get capitals, nobody can get credit? Nobody can start a business? They have to work for you and live like a peasant. 😂 

 They can, and who lends money will go bankrupt sooner or later. It simply does not work. That's why banks create central banks, to socialise the loss. Without central banks and with sound money, lending money simply does not work. 

 And it's not communist when people have to really work to get money, but practically no one will lend money.
