I believe we will go into default, and I don't think it's for political reasons at all.
Let me explain my theory.
There are only two dozen or so hardcore tea party members, all from gerrymandered districts, who are holding the House hostage. Somehow they have gotten Boehner in their back pocket, and he has completely stopped the government. Now, those tea party representatives are all from wealthy rich districts, very red and lots of money. We all know how skewed the wealth distribution is in this country, it's staggering how much buying power the top 1% have.
So, what do the tea party representatives really have to gain by doing all of this?
I think it's all big business, and I'll tell you why. If the country goes into default, it will not only plummet stocks across the world but send the planet into a recession, most likely a large one. Who does that hurt, and more importantly who stands to gain from such an event? In a devalued market, the wealth accumulated by the top 1% will decrease like everyone else's, but their portion of it will essentially become larger by extension, especially if they are invested wisely and prepared for it (if they know what is coming). They will be able to buy up lower priced stocks, companies, real estate, all at much reduced prices. This is their end game, this is what they are after. They want to default the country in order to amass more wealth during the following global recession. While the 99% will be struggling to make ends meet the 1% will go on a firesale shopping spree.
It's all simply a huge business opportunity, and they are willing to crash the country and the world to do it. And all of this political nonsense is just the smokescreen to camouflage it all and make it more believable, more palatable. They don't really care about the ACA or the debt ceiling, both of those things are inconsequential to the rich like them. My guess is that the 1% have bought off Boehner, because they absolutely need him to hold this line in order to default the USA.
Basically, the 1% have succeeded in hijacking the US government in order to make a very large and profitable business move that will allow them to acquire and amass even more wealth and power.
That's my theory. I think they want to default, it's been their end game all along, and they have no desire at all to prevent it from happening.
