true. and there is also the greedy government factor. and other greedsters. look and you will discover, many cities impose home building moratoriums. reason: by stopping building homes, you drive up the existing prices of homes. creating more property tax revenue, without the cost of more services. and the tax money rolls in. and the government workers get huge wage increases with massive benefits. and low income labor moves into tents. big home builders bribe government to create gobs of new building regulations. that only a big builder attorney can comply. and then there are those who block better and less expensive ways to provide family homes. and again politicians pocket money to keep new technology out. this is what uncontrolled capitalism does. make the rich richer. and make labor poorer.
