Trump says "We'll let Obamacare fail":

Incredible, but it appears Trump is more interested in getting back at Obama than in actually improving the U.S. healthcare system.
Then again, it shouldn't come as a surprise. Because, if you look at most of the executive orders Trump has signed, you'll see that most of those orders have been specifically made to undo Obama's legacy:

Which is why I believe Trump wants to see Obamacare fail, because the program (despite being called ACA) is popularly known as Obamacare, thus it has the name Obama on it. It may be as simple as that. In Trump's mind: Obama = very bad, therefore Obamacare = very bad healthcare.

According to a NYTimes editorial (link above):

"While the Affordable Care Act is not collapsing, the Senate and House health bills and President Trump’s promises to sabotage the A.C.A. have destabilized some of the health insurance marketplaces created by that law. Nearly 40 counties in Indiana, Nevada and Ohio are at risk of having no insurers participating in the marketplaces next year; other counties will have only one company offering policies."

"In addition, policies sold in the marketplaces could cost a lot more if the Trump administration carries out its threats to stop providing subsidies to insurers to lower deductibles for low-income and middle-income people. It can do that through administrative action."

Knowing Trump and his use of executive action to undo Obama's policies, Trump will probably take all necessary steps to sabotage Obamacare. But then what? Despite having a majority in the senate, the republicans don't appear capable of passing a healthcare bill which they can all agree upon (republicans can't even come to a consensus amongst themselves, let alone reach across the aisle to Democrats).
Trump & the GOP first need to understand the dynamics of the senate and the country, in order to then do what's best for the people of the United States.

But I'm not too optimistic, since Trump doesn't seem capable of understanding the huge implications of letting a huge healthcare program (which is providing millions of Americans with health insurance) fail.
Case in point; the fact that the program is popularly called Obamacare appears to be at least one of the reasons Trump wants to see it fail.
