Things are not necessarily as bad as they seem to you, the FTC does, in fact, have a good deal to say about behavioral marketing here is a link regarding their latest actions:

It is not surprising that the Reg would pay more attention to what is happening in the UK and Europe on the topic of behavioral marketing, but that does not necessarily imply things are quiescent in the US.
I would not, BTW, characterize the US as being "most directly democratic country in the world". The Swiss, for one, have a form of initiative and referendum at the national level, whereas we do not. I think a more accurate characterization of the US would be something like most institutionally mistrustful of concentration of power.
Parliamentary systems do not separate Legislative from Executive power to the same degree as in the US. This, mind you, is a structural feature which can be overcome by circumstance. If a President ends up with a supine Congress (as has happened from time to time, including recently) this check on Executive power becomes more theoretical than actual, at which point Presidential power is mainly limited by what the Supreme Court is willing to allow. The price we pay for this is that it is entirely possible for the President and Congress to be at cross purposes (as, for example, in the Gingrich-Clinton budget showdown). Fortunately (from my perspective) a Congress at loggerheads with a President is more the natural state of things than a rubber stamp Congress. It may make things harder to accomplish, but I feel that is a price worth paying.
