Recently? I hear the same moniquer since 1989.
The thing with pessimists is: They are always right.
When someone shouts fire 5 times a day, every single day, eventually something will burn close to him.
And he can happily proclaim: "See? I always said it."
I also think that the rules of the game changed with the move from gold-backed money to digital means of exchange.
Gold is a rare finite resource. While digital means of transaction can be produced indefinitely.
What's the role of governments in this world? Keeping a few prices stable:
Food & Beverage, Rental Fees, Education, Energy - these are basic items people need to survive. When they have it, they are in balance and rarely have ideas like starting a civil war.
Everything else can be inflated and that's fine. We see this in real estate prices and the stock market.
