The quest for a modern low-tech fighter

Hi guy’s,

Just a quick one, love it or hate it the US is one of the top three fighter aircraft manufacturers and exports to nations worldwide. Problem is they seem to be concentrating their efforts on the F/A-22 and F/A-35 whilst ignoring smaller, less wealthy nations in Africa and Latin/South America that cannot afford to purchase or maintain aircraft costing millions of dollars. So why don’t the yanks design and build a low cost/low tech fighter for its smaller allies like the F-5 of old? Are they just handing these nations to the likes of China (not that this is a bad thing) to sell the JF-17 (or whatever its being marketed as now) or do they plan to finance the construction of the high tech facilities needed to operate even the F-16C/D.
