What was the most profound consequence of Shays Rebellion?

Farmers were taxed more

The most profound consequence of Shays Rebellion was the refusal of the farmers and others to pay their taxes.

Explanation:

Shay's Rebellion (1786) was an uprising against the state of Massachusetts's unjust economic policies and political corruption. The state had imposed heavy taxes on the farmers with many facing foreclosure of their lands.

This revolt was led by Daniel Shay, a former Revolutionary War soldier, who himself was levied taxes even during his absence. Moreover, the government hadn't paid him for his services so he had no means of paying his debts. He also found out that more people were in a similar situation like him. So, farmers took the courts to stop their lands from being foreclosed, resulting in them not paying any of the taxes imposed.
