Is Donald Trump improving the US government?
I don't have a simple yes/no answer to this, since it's a genuinely contested political question that depends heavily on values and priorities—and I also don't have information past my knowledge cutoff about his current term.
What I can do is lay out some of the major areas where his actions/policies are debated, so you can weigh them yourself:
Areas of debate:
Why I won't just give a verdict:
"Improving" implies a value judgment—improving for whom, and by what standard (efficiency? fairness? adherence to precedent? economic outcomes for a specific group?). Reasonable people disagree sharply on this, and I'd rather help you think through the specific policy or action you're curious about than hand you a verdict.
Is there a particular policy area or decision you want to dig into? I can give you a more substantive, evidence-based rundown on that.
