1) How can lobbyist "capture" government?
2) Unless I'm mistaken, the SEC was created by congress in 1934, and is not considered a private enterprise.
3) A military industrial complex would by definition be comprised of both private industry and the Pentagon. Not exactly "privatized power".
4) What do private prisons lobby for? Keeping drugs illegal? Maybe they do, maybe not. Does that count as "privatized power getting out of hand"? I'm not sure it does.
5) Solyndra? Really? That was congress AND Obama, and it was pure payoff, not "crony capitalism".
6) Apple's exploitation of labor happens largely in China, and for some reason most of the left doesn't give a $#%@ about that. DR has a history of detailing Apple's transgression here on this site, which you can find easily using the search function.
Your final statement, "Private interets (sic) using government, government using itself or private industry to create corruption" is too vague, too nebulous to address without clarification.
