incredibly VS to an incredible extent
Please compare the two followings:
1)"In the 1960s, Korea experienced a rapid industrialization. Although it incredibly developed the economy, it also intensified the gap between the haves and the have-nots."
2)"In the 1960s, Korea experienced a rapid industrialization. Although it developed the economy to an incredible extent, it also intensified the gap between the haves and the have-nots."
Do you think "to incredibly develop the economy" is not natural? Thanks!
