You don't know that Congress includes the House of Representatives? I did not "intentionally omit" anything. And I also mentioned the electoral college, which you "intentionally omitted".
Yes, that is exactly correct. Not only can laws only pass with the approval of both houses (they each have veto power over the other), but the Senate has extra privileges such as judicial and cabinet appointment approvals that do not allow direct representation. And stupid rules like the filibuster just amplify the effect.
Ironic, isn't it, that while the American revolutionaries did not like taxation with representation, they deliberately created a system which, with the passage of the 16th amendment, enables just that.
