There are no fundamental differences.
Since their inception, both parties have oscillated back and forth with their ideologies based largely on monetary incentives from corporate sponsors.
The Republican and Democratic party are merely political actors controlled by behemoth sized financial actors to "divide and conquer" the american population in order to decrease their political energy and allow their agenda to unfold.
A forthcoming article in Perspectives on Politics by (my former

evidence employed by Gilens in his landmark book “Affluence and
Influence,” Gilens and Page analyze 1,779 policy outcomes over a
period of more than 20 years. They conclude that “economic elites and
organized groups representing business interests have substantial
independent impacts on U.S. government policy, while mass-based
interest groups and average citizens have little or no independent
influence.”

The Federal Reserve system was designed to be a trap. The intent of the bankers was to trap the U.S. government in an endless debt spiral from which it could never possibly escape
