Romney certainly knows what strategies offer the best ROI for shareholders, [after his company gets their enormous compensation], but that doesn't translate into creating the jobs that we need to get out of the mess we're in. Jobs mean increased tax revenue and consumer spending, which creates demand for products & services that create demand for more workers, etc. Romney is part of the trend to reduce labor costs by whatever means possible, which leaves Americans on unemployment. [Not to mention being insulted by the very people who put them there calling them 'gimme goobers' & the 'entitlement class']
Without the jobs, the government is short of funds while demand for the 'safety net' increases, which is just about where we've been stuck for years.
If Romney really wanted to create meaningful growth [to the entire country, not just the CEO, management & shareholders], he had plenty of opportunities to do it at Bain, but he wasn't interested then, and I don't believe he is now either. And please don't say 'that wasn't his job', because wanting to strengthen your country in whatever way is in your power to do it is everyone's job. He utterly failed.
PS Just read that Wellpoint [parent to Blue Cross] shareholders forced the resignation of CEO A Braley, because they're unhappy with the ROI over the past few years. During those years, the CEO's pay doubled[ from 6 million to 13], and that's a common example of how business works: subpar performance earns millions, while those who do an excellent job lose it.
Romney won't change that, it's how he works and all he knows.
