You're assuming the landlord owns the property free and clear. Perhaps the landlord has a bank loan, but certainly has to pay property taxes with or without a tenant.
In the distant past most people had children not simply because of a want, but also a need, to help perform the daily tasks necessary to provide for their survival. Today, many people have children they knowingly are incapable of providing for, and others who are capable of providing for until they become adults but with no available employment opportunities for them to avail themselves of once they become adults. IMO, population growth has become the major contributing factor to most all our problems. As such, government has taken advantage of the situation NOT to solve anything but only to impose greater control being exercised from a central location. Today, again IMO, we are no longer a Republic, comprised of Republics as once guaranteed by Article IV, section 4 of our U.S. Constitution, but instead have become more of a Unitary State based upon a collectivist agenda. The Federal Reserve Act, created in 1913, at the behest of some of the wealthiest Americans and brought to fruition as a result of the 'Great Depression" has put us on a path of constant accumulation of debt and inflation insuring the wealthiest from loss by eliminating the possibility of offsetting periods of deflation from occurring in the future.
I have yet to see a suggestion which would reduce the wealth of the wealthiest or decrease the gap between the poorest and the wealthiest. All so called solutions at best can ONLY reduce the rate at which the gap widens, and for those who are working a slower rate does not necessarily produce the best results. People tend to be very protective of their property and wealth is not so much the dollars one possesses, but any currency which it can be exchanged for.
