My opinion: Any progress made on the economy during Obama's presidency was made in spite of his policies, not because of his policies. He was the most anti-business president in modern history, with many quotes available that would tend to support my opinion. It is only the drive to succeed in business that might be responsible to the meager growth during his reign.
Further, in my opinion, the great strides the economy has made during Trump's presidency is because business feels they can risk expansion with little risk of being consumed by multiple debilitating regulations. The business climate is much more favorable for growth without penalty. A lot of it is psychological.
Finally, in my opinion this country was built on and will thrive on entrepreneurs who are willing to move forward and reap the benefits of the risks they take without a massive bureocracy sapping the life out of the fruits of their efforts.
Now you can rangt and rail all you want, but this entire post is my opinion. Deal with it.
