To what are the representatives at the convention referencing when they state, "the impropriety of delegating such extensive trust to one body of men is evident"? the powers of the states and the federal government should be kept separate. they understand from experience what it is like to live under a king's rule. it is not wise to have only one house of congress. the constitution must fully vest power in the federal government

The rise of advertising in the 1920s. i am good with seeing how advertisements shape the roaring twenties and how it developed a new way of life through modern days. but i am not sure what the details of advertising in the 1920s were. if possible can you send me links (preferrably credential links) to sources that maybe show like the first company to start advertising through the radio, how advertising benefits (statistics graphs), etc.
