Important economic indicators in american business?

what are important economic indicators that might either support or refute an argument

its not specific as to what you want
but still try CPI - consumer price index it is a for a goods of basket an avg consumer purchases, real growth rate of GDP or on the basis of purchasing power parity, Gdp in itself can be used for a lot of info like the size of the country , gini index can show the distribution of wealth in the country. I hope this helps just be a bit more precise as to what exactly do you want to prove.
