You are not a serf. Grow up.
Sinking into bitterness and despair will not help you improve your economic outlook. If anything, that will make it worse.
In medieval times, a serf was someone who worked on a lord's land and provided produce for the lord and himself. He did not own the land where he worked, and could not leave. It was a brutal existence, without modern heating, absolutely no air conditioning, and no modern medicine. Listening to a young man today defiantly proclaim that he "will not be a f*****g serf" by working a low-wage job, given the brutal reality of serfs in medieval times, is laughable.
One could argue that the modern economy provides little ability for someone to move up and we need political reforms to restore income and class mobility. If we assume that to be a fact for the sake of argument, what exactly are young men supposed to do about it today? Should they live on welfare? Should they never leave their parents' basements? Should young men fall into bitterness and despair? Or should they try to get a job and provide for themselves, recognizing that stability is not what it used to be? Could a young man take a risk and start a business?
In some of the "man up" discourse, some have argued that you are "supposed to hate your job." Recognizing that most people are likely to have a job that is unpleasant at some point in their lives, much of that is your attitude. I fell back into retail in my early 30's, and it would have been very easy to be bitter. But I genuinely enjoyed my job. My physical health actually improved because I was more physically active, rather than sedentary. Having a positive attitude made that experience much better than it would have been otherwise. I also had a "moment of clarity" about halfway through that gave me peace, and I will always be thankful for that lesson that disciplined my pride and my entitlement mentality.
Young men, it does not matter how you feel. It does not matter that life is "unfair" or that the old days were better. (You should probably consider Ecclesiastes 7:10 if you think that way.) You need to work. God's Word makes this clear in I Timothy 5:8 and II Thessalonians 3:10. You also need to be thankful for what God has provided for you. Every generation has had its challenges, and life has never been easy. That does not mean we should wallow in misery and despair, refusing to take responsibility. Live by faith.
No one should ever hate their job. If you hate your job, you choose the wrong field. I just wanted to BE a mom and a wife but doing that was never allowed to happen because my generation of men ARE the adulterous generation.
