So it’s possible that big companies are increasing their market power by
using lobbying to capture politicians and regulators. If this is true, it’s
very bad news for free markets and capitalism. It would validate the claims
of Senator Bernie Sanders, the socialist presidential candidate who has
blamed corporate interests for the woes of American workers.
I'm not sure how the conclusion follows from the premise. The rest of the article talks about how increased regulations, rather than helping the consumer, just give corporations more avenues by which to lobby the government and suppress competition. But somehow that supports the claims of Bernie Sanders, whose platform calls for massive increases in corporate regulation? That seems like dubious logic to me.

It doesn't mention his platform of regulation, just his "blaming corporate interests". Which is quite the bland statement overall, no matter where it lies on the truthiness scale.
