> Companies buy/merge competitors all the time that passes FTC legal review. E.g. Boeing acquired competitor McDonnell Douglas. Hewlett-Packard acquired Compaq Computer.
These are mergers that were allowed, but probably shouldn't have been because their industries were already quite consolidated by that point.
The ones that should be okay is when e.g. a company with 4% market share wants to buy a company with 0.5% market share. Companies merging when they each already have double digit percentages of the market is craziness.
> It's been leaked that the US Govt is encouraging competitors Intel and AMD to merge ... so the USA semiconductor industry can be stronger and thus, less dependent on Taiwan TSMC and stay ahead of China.
This sort of thinking is a demonstration of incompetence. AMD and Intel can both design competitive processors. AMD sold their fabs and now has the processors made by TSMC. Intel still makes them but their manufacturing process has fallen behind, to the point that they too have used TSMC to make some of their products. Saddling AMD with Intel's uncompetitive process would only put them both at a disadvantage against other competitors using TSMC.
The real problem here is that Intel was too vertically integrated and focused on producing only its own designs on its fabs, and then abandoned the low end of the market to sustain its margins. Which allowed TSMC to capture enough market share that the larger volume gave them enough capital to take the lead.
What the US needs is not mergers but the opposite -- its own TSMC as a competitive contract fab that can do the volumes needed to sustain a state of the art process.
