Although certain laws have been enacted since, RBC contributions can be funneled through less conspicuous means, lobbying for one.

This is to show you how politicians are BOUGHT by banks.

Here is a small record of RBC donations in the U.S.. Keep in mind, that these are only public sources, and the actual figures may be hidden through complex ways that never meet the publics eye.

Now this excerpt below is taken from the ICIJ news that just came out on HSBC;

Meanwhile, in the United States, the HSBC North America Political Action Committee (PAC) has recorded its second month in a row without making any donations to U.S. politicians. The PAC rarely goes a month without making any contributions, however it is unclear whether the lack of activity is linked to the Swiss Leaks revelations.

The main point of this post is to show how banks INFLUENCE politics. Through this understanding, it may be easier to understand why politicians and government regulators, have not acted for SLI investors.
