By improving your own education, working hard, and learning good financial habits, you can be at least somewhat better off. You will always suffer at the hands of this capitalist machine that chews the poor and spits them out. But with some level of self-discipline you can (at least slightly) improve your life and the lives of your offspring.
Lots of success is based on probability, so with luck, hard work, and financial literacy you may even be much better off.
I am reminded of working with poor clients when some consumer bank in the US started offering a "financial health" program, wherein they would round up every card purchase to the next dollar, deposit that fraction of a dollar into a savings account, and then match it for you up to $100 a month.
All the other counselors at our org were super excited to tell our clients about this: "It's free money from your bank! You just got to start making a lot more transactions on your card to earn out the full $100!"
What really works is giving up on yourself and admitting that you will die broken, sick, and poor, and putting all your energies into your offspring who will vindicate your sacrifice. Pressure your children into challenging academic pathways, reduce their leisure time, and help them get into prestigious occupations. That's the only reliable path to building family wealth.
