At least part of Donald Trump's boastful plan to "Make America Great Again" could lead to another recession if he is allowed to execute the mass deportations he has vowed to carry out.

Up until now, Trump has been scarce on details as to how he plans on turning around the country's economy, but he recently opened about when was the last time he thought the country was striking the right balance between defense and trade.

"If you look back, it really was, there was a period of time when we were developing at the turn of the century which was a pretty wild time for this country and pretty wild in terms of building that machine, that machine was really based on entrepreneurship," Trump recently reflected of the time around the 20th century and again immediately following World War II.

Trump Also Loved the Lated '40s and '50s

Trump also fondly recalled the "late'40s and '50s" as a time when he insists the U.S. was not to be messed with and everyone respected the country.

"We had just won a war, we were pretty much doing what we had to do," he added.

Trump has been just as adamant in vowing that a big part of his economic recovery plan for the country would include deporting all 11 million undocumented immigrants now estimated to be living in the U.S.

Study Finds Mass Deportations Would Lead to new Recession

His view has remained unchanged despite the findings in a new American Action Forum (AAF) study that concludes such an act would cost the country somewhere in the neighborhood of $400 to $600 billion over a 20-year period and ultimately reduce the overall size of the economy by a recession level of 5.7 percent.

The AAF report adds such steep costs would be dwarfed by the $1 trillion hit such a move would deal to the U.S. economy. Ultimately, all the machinations are projected to trigger a collapse easily on par with the Great Recession all over again.

Yet, there was Trump recently doubling-down on his mass deportation vow during a recent presidential debate in Houston, where he also reaffirmed his pledge to carry out the deportations early in his administration.

"They will go out," he said. "They will come back - some will come back, the best, through a process. They have to come back legally. They have to come back through a process, and it may not be a very quick process."

As for his view of when America was last great, Trump also failed to look upon the Reagan administration with much fondness.

"As much as I liked Ronald Reagan, he started NAFTA," he said. "Now Clinton really was the one that - NAFTA has been a disaster for our country, O.K., and Clinton is the one as you know that got it done."

The nearly quarter-century old North American Free Trade Agreement, signed by former President Bill Clinton paved the way for free trade between the U.S., Mexico and Canada.
