You wake up as one of the founding fathers during the closing days of the American Revolution...

Obviously the first thing I do is write a critique of capitalism a century before Marx.

Maybe I'll even become known as the founder of economics before Adam Smith.

This, write Das Kapital before Marx

The Hidden Wealth of Nations by Alexander Hamilton

Alternatively

Pretty much this

Abolish slavery ASAP. That shit's going to bite us in the ass later unless we do something about it. I guess it would also be fair to start advocating for more workers rights.

They wouldn't understand what you're saying since there haven't been any political parties formed nor does anyone intend to start any yet

Madison, Hamilton and Washington would never be seen again

Also would try to have Thomas Paine help with the constitution instead of going to france.

This.
