Bottom line is that the government is going to do everything in its power to try to avoid a 2008 repeat.
I'll disagree with your assessment, but this is a very complex issue. I could type out a long thing detailing all the issues that the fed created, but it essentially follows a path like this.
1. Gubmints tells home owners "12 months no pay woo"
2. Servicers go "Um, now we're obligated to buy those loans out of MBS because of rules since 2008 that were supposed to make them safer, we cant afford that!!"
3. Freddie Mac/Mae "Don't worry, we'll just sideline that little rule about buying bad loans out of MBS for a bit.
4. Anyone with a MBS "Uhh, I thought these were safe now, we're going to get paid on time, right?"
5. Mac/Mae "Don't worry, servicers 100% can pay their MBS payments even if a few people default. This is just a blip no problems"
6. Servicers "WE FUKKKIN BROKE ALREDY"
7. Mac/Mae "We'll back up services temporarily with our billions its cool"
8. Mac/mae 2 days later "HEALP CONGRESS"
<you are here>
And that's why the Fed now holds TRILLIONs in MBS, I believe its their majority holding. The banks are back to thinking they are worth less than they appear to be just like 2008, so those that have them are shoveling them onto the fed who is buying them at face value in an attempt to keep the perceived value up. Will it work? Who knows. But I think our current actions are moving us toward 2008, not away. Loosening MBS rules in particular is a concern.
