I'm not sure I understand the question. None of these are mutually exclusive. Obama could have built wall AND not separated families. The truth is, he DID separate families but as an exception, not the rule.
Obama would have also built 700+ miles of wall but republicans blocked it from even being voted on in the house.
As for the economy, I give a president two years though usually they do little to affect it. Trump is different. He makes stocks fall with a tweet. No other president has done that because no other president attacks private companies or starts trade wars.
You are correct.
Not mutually exclusive and, in fact, deeply intertwined.
Continuity of long range planning and incrementalist boiling of the frog...
Not sure why all the outrage then...
Not sure they are deeply intertwined.
Also, what long range planning?
Outrage is mostly because of the justification, not the actual plan (in some cases)
Ex:
I've spoken to Border Agents and they feel that 300 miles of additional fencing plus upgrading and repairing of existing fences at these ares will aid them in their patrols and force border crossers to safer, official ports of entry.
Vs
We need a big, beautiful wall to keep out the rapists, drugs, and murderers comming across the southern border. All of them are evil, horrible people who will destroy America!
One is political, the other is fear mongering.
