You might have what it takes to walk the walk, but don't jump to conclusions before you've trod the path of a truly awful economy.
My point was that once upon a time, companies and their employees were likelier to stick together through good times and bad. These days the equation has changed: companies are liable to dump you when quarterly profits aren't good, and you're likely to dump a company at the first whiff of something better. That's better in some ways, but I think we've also given up something that may be harder to quantify. For instance, if you're a happy worker and not worried about the next quarter, you can also invest in the company long term, rather than strictly looking out for your own interests, and vice versa, even if there's a bad quarter. Said companies also had time to invest in things like creating Unix, and lots of other R&D that wasn't immediately registered as profitable.
I don't know that I'd be happy like that, and I think that the cream of the crop in today's world oughtn't look to other people's companies as a place to make their mark; still, I think it's something that bears thinking about. Perhaps the pendulum will swing back at some point in the future.
You're 100% correct though, I have no problem limiting my tolerance for bad situations these days.
