I don't see much support for these claims. He's been in office for two months, so we lack any real data and can't make claims about his impact. Almost certainly, the prior government (President and Congress) has much more impact on current conditions. For example, consider this point in Obama's Presidency, when the Great Recession had begun a couple months before he was elected; conditions on April 3, good or ill, were mostly the responsibility of his predecessor.

The claims about his motives and thinking are speculative; it would be hard to find evidence of them. Even the things he says about himself often turn out to be unreliable. Certainly we can speculate on many other motives and interests, but I don't think that's useful.
