While President Trump claims that he has single-handedly boosted the economy to its peak, his efforts are just a continuation of Obama’s economic growth. Following the peak of the 2009 recession, President Obama stimulated the economy with an upward trend. The economic boom of the Trump Administration was only possible with the foundation laid by President Obama. 
In addition, Trump’s tariffs have not benefitted the United States but instead started trade wars with China and the EU. For example, the tariffs have already caused the loss of over 300,000 jobs and an estimated $316 billion in lost revenue by the end of 2020. Clearly, Trump’s tariffs are doing more harm than good for the economy.
