The economic value of having colonies in the first place was for 3 main reasons
1) attain cheap labour from the native peoples
2) acquire cheap raw materials to bring to the homeland (Europe)
3) open up new markets to trade with
the first two were vital in Britains industrial revolution. Without cheap raw materials, and cheap labourers, the factories and refineries in Britain would have costed far more to maintain and keep supplied. This, in turn, would have slowed down production considerably. There is no doubt in my mind that the industrial revolution would still have taken place in Britain with or without the colonies, but WITH the colonies the process was sped up considerably.
Overall, cheap labour and raw materials attained through Britains colonial interests sped up the industrialisation of the UK.

The supreme court decision under John Marshall leadership have extended federal powers, but not too much in the sense of destroying the federalist idea that brought the United States together. Marshall was guided by a strong commitment to judicial power and by a belief in the supremacy of national over state legislatures. His judicial vision was very much in keeping with the Federalist political program in line with the constitution.
It can be argued that someone not elected should not have power to shape government and law through the Expansion of the Judiciary in 1801, but the Marshall Court, and this decision in particular, established the principle of "judicial review" whereby Congressional laws and executive actions may be judged by the Supreme Court to be within the bounds of the Constitution.
It is definitely not appropriate that a political party ideology is implemented through the judiciary, however, In keeping with John Marshall's Federalist views, they generally favored strong government action and especially supported the supremacy of the federal government over state authorities as long as it was constitutional.
