Oh yes, most dystopian fiction still uses it.

And this is also an old rhetorical trick. In political speech it takes the form of putting two words as close as possible together to make people unconsciously do a link between them. "I will strengthen our borders to prevent immigration. Crime is the main focus of our policies." <- No links were formally made in that sentence between crime and immigration, but the words seem linked.

If you make a whole speech about Obama that also talks about the problems of lobbying and corruption of the elite, people will associate Obama with these concepts.

It is very easy and very effective.
