Motivation=Sex + Money?

In European workplace, people put a lot of efforts doing research on "motivation", trying to figure out what really motivates people to increase their productivities.
Yes! We all came across having a wonderful dream and vision of how we can be in the market place after we graduated with a glory. However, the reality is usually opposite to what we imagine, realizing that this society isn't what we expect and getting a promotion isn't that easy no matter high our education are.
We all have a plan to work all the way up to be an manager or director, we carefully measure what we can do in order to be successful. But it's difficult for us, people don't own a company, not knowing someone from the company or not kissing our bosses asses. This will decrease our motivation after couple months working at the company, but it is also sad that we cannot leave our jobs even we don't like/enjoy it. Because we might have a family to feed, a house to pay off, and so on, plus the whole inflation is like a butterfly effect affects every country glob wide. This suck economic society keeps us stay in where we are, just to make some life and not to end up in the street.
And then, here comes the problem, many companies start to layoff their employees might with reasons, such as the company is closing down or cutting labor costs, or without reasons, like we don't need your service anymore or replacing my relatives/friends first and so on.
Some companies will even hire consulting companies which also called "efficiency management" to investigate employees' productivities, and reporting to our bosses, so that our bosses can decide who can stay and who should go. For what i think about this, i really feel unfair for having outside company to give me interview and monitor me for the whole week, these consulting companies do not work at my firm, they know nothing about what my job but viewing us in their own professional perspectives.
Yes!!! Telling them that i got a family to feed, having a car and house to payoff are not going to be part of their considerations. So, we keep our nerves by increasing our productivities and hope we won't get fired. This kind of motivation is called "Fear" which i talked about last time and this is an forced motivation. How long does this motivation last? We don't know but we will need to do what we have to and exceed it even though we hate it. Fear can only motivate people in the short-term, as long as the economy gets better, people will leave without doubt.
People should have motivation by their own, in this way, people's productivities will be higher and our working environment will be pleasant. But what really motivates people to stay at a firm and work happily? The answer is "Sex and Money", no doubt, money always comes first, we all want more money so we can have a better life quality. And we are all willing to bend our knees if we get more salaries even if we know the company is trying to control us by using this. But how many companies are willing to pay more just in order to motivate us? Not many, you should feel happy that they don't cut your pay check or you don't get fired.
Therefore, many previous researches found motivation on jobs were expectation, enjoining the workplace, and so on which were not totally true. Yes, there are still some people who actually motivate by these factors. But why i said the real factors behind this research isn't true because many researches are done by quantitative means, we only have few options to choose when we are trying to complete the survey, it can be known that if there was not have the option we want, we leave it a blank, we won't even want to waste our time on filling out a survey, of course, we won't have time to write down what really motivates us.
