What lessons will these people learn, if nobody is being held accountable for the last crisis? Some of these corrupt Bankers got huge bonusses, after they "rescued"

their companies with taxpayers bailouts!
This was the reason why Satoshi created Bitcoin and we should seriously consider if we are still on track to achieve Satoshi's goals.

The next crisis will come in 2019 and it will be worst than the one we had before.

Bankers bonuses are a double edge sword, they are in the best interest of banks and shareholders in one way because they incentivize good and hard work, on the other hand they incentivize corrupt or improper practices to increase profits and gain bonuses. The best mix between the two in ensuring bonuses are payable in the future and are in stocks rather than cash.
Many people are calling a new crisis in 2019 but if it's so obvious then it won't be nearly as bad as 07/08. That came out of nowhere and that's why it was so bad, the worst crashes are always when people are unassuming and think everything is going great.
