Our economy specifically, and the nation in general wold be far better off if only property owners were allowed to vote.
I'm afraid I have to disagree. Of course, since I don't own real property right now I obviously have my own bias, but then again, so do those who do own.
Firstly, that makes a hollow mockery of the Declaration of Independence. "All men are created equal" - not if their right to suffrage, to participation in self-government, depends on the accidents of life. Those who, due to the accidents of life, do not own property no longer have the right to have a say in how they are governed: their consent is irrelevant to whether the powers of the government are just.
Secondly, that makes a hollow mockery of the Constitution. The First Amendment right to assemble and petition the government for redress is meaningless to me if I cannot wield the power to change that government if it ignores me. And what of my other constitutional rights? How will I protect those? I cannot influence the government (at least not peaceably) because I have no say in how it's constituted. The courts become a thin reed indeed, because the judges are selected by the politicians (president, with advice and consent of Senate), who are beholden to the voters, and thus by necessary implication, may ignore those who do not own property with impunity. The possibility of becoming a property owner in due course is also a thin reed indeed because the voters can throw all manner of obstacles in my way through their control over the government, to ensure that nobody other than their political favorites become property owners.
That reduces me - and millions of other American citizens - to the status of ward of the state, wholly dependent on the whim of the government for my very existence. I had thought that folks on this forum generally disapproved of people becoming wards of the state and generally wish to free people by reducing their dependency on the government.
Finally, that would simply lead to a bloody demonstration of the truth of the Declaration of Independence: That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
The idea is seductive indeed, but the reality is vile and insufferable.
