I’ve been thinking about interest rates for a long time. I keep reading in real estate newsletters I get and in articles I read in the newspaper that interest rates will go up soon. Now I’m not an economist or even a decent investor but I wonder what would happen if rates went up to a more normal level like 6%. Wouldn’t the interest on the national debt explode and devour taxes leaving nothing for anything else ? Doesn’t the Fed have to artificially suppress interest rates ? Haven’t they backed themselves into a corner ? Interesting informed commentary is welcome.
