The people that survived without the indians were the few. Most likely the wealthy.
People died from the winters in log cabins, sickness, and lack of food. New england were mainly farmers who didn't know how to hunt. Jamestown were soldiers who didn't know how to farm. And they were all living in those crappy log cabins. Poor folks didn't know straw was natures best insulator.
It was the indian introduction of corn, tomatos and root crops that improved the diet of the people. Cus wheat was really hard to grow in america. Also the indians taught the europeans how to fertilize and take care of farm land.
People with power push their will upon those without power. Just seems to be the history of the world.
