Key quote:

Here’s the problem with the belief that helping Wall Street always helps the economy: it isn’t true. In recent decades, Wall Street has grown bigger and financial sector profits have gone from 10% to 25% of total corporate profits, but everyone else in America has lived through a generation of stagnant wages and sluggish economic growth. Even today, big banks are making record profits and handing out huge bonuses as average wages barely budge.

The truth is that Washington has it backwards. For a long time now, Wall Street’s success hasn’t helped the broader economy — it’s come at the expense of the rest of the economy. Wall Street is looting the economy and Washington is helping them do it.
