Answer:
No, the U.S. is not regressing
No, it will not take over the U.S.
Step-by-step explanation:
No, the United States is not regressing because the poor country can boost their growth rate by taking the advanced technology from the developed countries like the United States. So it is easy to poor countries to increase their growth rate but for the developed nations who already using the advance technology is difficult to increase growth rate.
No, the country will not take over the United States because the percentage increase in GDP can be greater but actual value of GDP will be very high in developed nations.
