The advantage for US business in 1800 was that the government sold land at a low cost. The federal government had much land for sale at a rate of 1.25 Dollars per acre. Adjustments were made, and by 1854 the land was sold at an average price of 12.5 cents per acre where more than 2 million acres were sold. Lots of the land had been in the market for over 30 years before the reduction of prices by the federal government.
One form of resistance was slowing down the picking of cotton. Slaves would intentionally go slower so that they could have an easier time in the fields. This was combatted by the Southern Plantation owners after a while by whipping the slaves severely during their first picks and then mandating that they had to pick at least as much cotton every time after.
Another form of resistance was to run away. The Underground Railroad helped thousands of slaves escape to the north and to freedom.
