Will 4.5% rates fix us long term????

I'm not convinced that the new idea of 4.5% will fix our market long term.  Think about how many buyers jumped into the market just because they could get a loan the last three years.  This sucked up future buyers into the buy now mode other than waiting the year or two needed to really get on their feet and to actually be able to pay back the loan.  So will the 4.5% bring future buyers into the "NOW" and cause another decline of the pool of buyers that should be there 2 years from now, but aren't because of the too good to pass up 4.5%  rate?  Since when was 5.5,5.75,6% start becoming "terrible" rates.  Once again, I think that as Americans we are not wanting to subject ourselves to delayed gratification.  Would love to hear your thoughts........
