Was "fiscal conservatism" the origin of the Republican party?

From wiki:

The new Republican Party envisioned modernizing the United States, emphasizing expanded banking, more railroads and factories, and giving free western land to farmers ("free soil") as opposed to letting slave owners buy up the best properties. It vigorously argued that free market labor was superior to slavery and was the very foundation of civic virtue and true republicanism; this was the "Free Soil, Free Labor, Free Men" ideology.

Fiscal conservatism is just a GOP invented MacGuffin to give them cover when they employ their advisorial antigovernance strategy. Every time we put a conservative in charge they blow the deficit up and funnel money to their backers.

Then they cry fiscal conservatism when a DEM takes power and say we need to cut social programs. Fiscal conservatism is a lie people continue to believe in because they hate anyone getting a break that isn't themselves. Themselves or wealthy white men who they project their own ambitions onto.
