Investors can demand it, but that doesn't mean they're going to get it.
Investors can chose to invest elsewhere. The return on bonds needs to be worthwhile in order to sell them.
I agree with you that we are in an inflationary environment, however interest rates are lower than they've ever been in modern history.
Right, we're seeing short-term manipulation for political purposes. The point is that it cannot continue indefinitely.
Incidentally, destroying a currency is one of the tactics of socialism to allow them to take over the system.
If the Fed raises the interbank lending rate, other interest rates rise, like you said, so the banks can make money.
They don't set the interbank rate, the banks do.
This slows demand for borrowing and takes the pressure off of the housing market, reducing the inflation of housing prices.
It does slow borrowing, but house-prices are subject to other factors such as demand, employment and the cost of building materials and labor.
Since the Federal Reserve was created in 1913, the American dollar has lost at least 98% of its value. Coincidence?
Exactly - this is the pattern of all fiat currencies (many don't last that long) and the challenge of storing wealth over extended periods (decades). People traditionally used gold for this.
Fun fact: the US once outlawed gold and forced people to sell it to them at below market rates, then raised the prices once they had it. The government is not there to protect your wealth - they are there to protect their power over your wealth.
