A Specialized Congress of Experts: Instead of Jacks-of-all-Trades

Congress has grown too excessive from when it was first adopted with only 13 colonies,
& far less confusing topics.
Thus, the plague of too many non-expert persons voting per important decision exists.
------------------------
Answer: House of Rep. voted in (assigned) by their Specialization:
creating smaller voting groups specific to 1 major topic:
Each group only votes on its minor topics.
ie;
Financial (30 repr.)
Human Rights (30 repr.)
Ecology (30 repr.)
Animal rights (30 repr.)
Government (20 repr.)
Health (40 repr.)
Poverty (30 repr.)
International (30 repr.)
Agriculture (30 repr.)

Exceptions: The decision changes of going to War
and changes to the Voting system, which would be voted upon by all groups.
