The serious damage of open borders and lack of industrial productivity isn't just going to be fixed easy without acting like a dictator.
Well, before you even
begin to worry about how to
fix these things, you need to show that
there even is a problem that needs to be fixed.
Could you provide hard evidence for any damage (much less
serious damage) due to open borders? Could you even provide evidence that any US international border
is "open" in any reasonable sense?
If it is, how do you explain the decline in net migration rate?
Does the US lack industrial productivity? What should the industrial productivity target be, do you think, and why?
Doesn't look too bad to me. At least it's
five times the horrific levels seen in the middle of the twentieth century.
It seems to me that your problems exist in your imagination, and were placed there by those people who seek support for "acting like a dictator".
And so, by repeating their outright lies (that borders are open, and that industrial productivity is lacking), and using these lies as the basis for your reasoning, you reach a conclusion that "acting like a dictator" is justified, having explained to your audience in the process that you have been
suckered by a bunch of liars into calling for an end to your own freedom.
You may be surprised that this is not seen by your audience as a very good justification
at all for kowtowing to a wannabe dictator.
Indeed, you seriously ought to reconsider your position, in the light of the fact that the guys you support have been systematically feeding you lies, and that your beliefs about the things that need to be "fixed" are (as a result) horribly naïve and objectively false.
The thing that urgently needs fixing (if you care about the constitutional foundations of your republic) is the clear and present trend towards allowing a dictator to take over, and to destroy those foundations.
