"effective antitrust enforcement, and escape regulatory capture"

Give me an example where Antitrust was actually breaking any monopoly.

In the EU and the Microsoft antitrust case, the remedy was to give the best poison to the competitors (free software Samba in that case) in that case royalties over patents.

Antitrust don't work, fines are too low, remedies are not working, and the administration is biased and politicized.
