My knowledge of what a “agency mortgage-backed security” actually is, is a bit sketchy.
Looks like you know more than you think. Mortgage-backed securities
are a bit sketchy.
But after looking it up on investopedia.com, and wikipedia, it seems like this is about the government buying large amounts of property/land etc.
Yes. But no. See, when you or I "buy" something, money is deducted from our accounts, credited to someone else's account, and we get the goods. But when the governments buys something, they can do the same thing, but they also have another option. They can employ
quantitative easing, which essentially just credits money to the seller's account
without deducting it from the government's account. That is to say, they simply pull the money out of thin air, magically increasing the money supply and causing inflation. (In case you don't know, inflation and deflation is simply what happens when the law of supply and demand is applied to money: increased money supply + same demand for money = decreased value of money. This is the primary reason why stuff costs more than it used to.)
Now unless I’m completely misunderstanding this, what does agency mortgage-backed securities have to do with economic growth, and labor markets?
It sounds more like the government taking things out of the equation, that’s not growth, it’s just shrinking the playing field.
Am I misunderstanding this, or is this as convoluted and confusing as it sounds?
It's not confusing at all, if you remember one thing:
Cui bono? When inflation sucks the true value out of your savings account, where do you think all that value goes?
Inflation is an invisible tax on everyone who owns money. That's why the government will use every excuse they can come up with to justify increasing inflation. It's really that simple.
Okay, it's not really that simple, but the basic principle is.
