1. It's unlikely that the 1% own more wealth in the US than at any other time in history. You're probably referring to the Oxfam report which is both potentially somewhat inaccurate and is talking about worldwide wealth.
Nope, talking about this:
Notice how it's not even the top 1%. It's the top 1% of the 1%. Guys like Warren Buffet are doing
awesome. It's all due to timing the market and buying stuff when there's a major crash. Warren Buffet is able to buy stock and businesses at the bottom. People like you and I typically don't buy at the bottom; we conserve cash because we're busy worrying about losing our jobs.
2. ARMs comprise a relatively small fraction of the overall housing market.
16% have ARMs.
Some of the people with an ARM did ok, but imagine 10% of the houses in your city went on the market at the same time. It would cause a housing crash. What do you do when you have a regular mortgage with a fixed rate, but your house now has negative equity? You mail your keys to the bank and walk away. More houses on the market. More real estate crash. More keys mailed to the bank. More crash. Doing this is called a "strategic default" if you want to learn more about it.
3. The kind of people who generally take out ARMs are not the same people who tend to have a lot of stock holdings.
You can't generalize like that. Banks were advertising that people should lever up to buy stocks. They're doing that again right now actually. I've received a few offers in the mail that I should get a home equity loan and use that money to buy stocks. It's a good advertising ploy if you think about it. "It's like free money! Your home equity loan cost 3% but the S&P might go up 20% this year! Come borrow money from us and we'll make you rich!"
Of course, that's where this next graph comes in. When stocks are at or near all time highs, people tend to borrow money to buy stocks. That includes home equity loans. That includes margin loans. This also happened in the 1920s. People would borrow lots of money to buy stocks, and they would often use their house to get that loan. I still remember some of the ads during the dot com bubble when my dad watched CNBC. There would be a guy with a $50 bill saying something like "to me, this can buy $1000 of stock" and my dad would yell at the TV and say those people are nothing more than gamblers
Maybe crashing the market wasn't their #1 goal, but they certainly knew it would happen. It always happens. They seem to be more careful this time. Janet Yellen is constantly moving the goal posts. They said they would raise rates when inflation hits 2%. It hit 2%. Rates did not raise. Then they said employment was the thing to watch. Employment dropped below 6%. Rates did not go up. Now they're saying things like "considerable time" to ease the market and prevent a panic. Even
talking about raising rates makes the market shake a little. Yellen seems to at least be giving it some effort to prevent a crash. I don't think she'll succeed, but I appreciate the effort.
