I feel like more aggressive anti-trust action that breaks up huge companies and reduces barriers to entry and we cang et back to the lean, competitive capitalism that leads to growth and innovation
Breaking up big companies is just the first step and relatively a minor one compared to the many barriers to competing with large incumbent firms. Industries with oligopolies where a more aggressive anti-monopoly policy would makes sense are almost always heavily regulated and in bed with the US gov. So that would only be the starting point if you expect them to continue to exist and not just get acquired.
This is more of a problem for medium companies wishing to not get acquired, not so much a roadblock from small firms.
