I want to become extremely wealthy, not for luxury, but to help people. What career path should I pursue?

I grew up in a pretty difficult household. My father was incarcerated for most of my childhood, and my mother struggled with alcoholism and had a difficult upbringing herself, coming from an immigrant family.
I think my childhood experiences have shaped what I want out of life. More than anything, I want to become incredibly wealthy. I’m talking about $200 million or more. I realize that might sound unrealistic, materialistic, or even shallow, but I genuinely feel like financial independence and having that kind of wealth would make me incredibly happy. That is what I prioritize more over anything else.
It’s not necessarily because I want designer clothes, expensive cars, or an extravagant lifestyle. Those things would be nice, but they’re not what motivates me.
What motivates me is the idea of having enough money to completely take care of myself while also having the resources to make a meaningful difference in other people’s lives every single minute of mine and having the financial ability to do so.
I think a lot about people who grew up in unstable households, experienced poverty, had difficult childhoods, or simply never had the opportunities that others have. I care most about being in a financial position where I could help those people financially, fund organizations, donate substantial amounts of money, volunteer, and dedicate a significant part of my life to philanthropy.
Ideally, I would want to build wealth in a way that allows me to give back continuously daily. I wouldn’t want to simply accumulate money and keep it to myself. I would want to learn how to invest it, grow it, and use the returns to fund charitable initiatives and help people who genuinely need it.
The problem is that I have absolutely no idea what career path would align with these ambitions.
Whenever someone asks me what I want to study, what degree I want, or what career interests me, I struggle to answer. My mind almost exclusively goes toward entrepreneurship, business, investing, economics, because my biggest goal is wealth creation to be able to help others. I don’t necessarily have one particular industry that I’m passionate about. I’m more interested in understanding how people build enormous amounts of wealth in the first place.
I’ve considered different possibilities:
Entrepreneurship: Starting a technology company, financial services business, consumer brand, or another company that solves a problem affecting millions of people.
Investment banking/private equity: Learning how businesses are valued, acquired, expanded, and how large amounts of capital are managed.
Investment management: Understanding how to build and manage investment portfolios and grow substantial wealth over time.
Real estate: Acquiring properties, developing housing, owning apartment complexes, or eventually building a real estate investment company. I like the idea of incorporating affordable housing into something like this.
Technology: Becoming involved in software, developing platforms that solve major problems, or founding a technology company.
Business acquisitions: Buying existing businesses, improving their operations, expanding them, and building a larger portfolio of companies.
I understand that building $200 million in personal wealth is extraordinarily difficult and that none of these paths guarantees that outcome. I’m also not interested in doing anything unethical, exploiting people, or sacrificing my values just to become wealthy.
I’ve even thought about potentially marrying someone who is already extremely wealthy, but I don’t want to rely on that as my life plan. I wished that I could as it seems easiest but that’s surely not a safe plan. I’d like to develop the ability to create wealth independently over anything.
My questions are:
If your goal were to eventually build a net worth of $200 million or more, what career path would you seriously consider?
What degrees would be most useful? Economics, finance, business administration, computer science, or something else?
Would you recommend pursuing entrepreneurship immediately, working in finance first, or gaining experience in an established company?
What industries or business models have the greatest potential for building substantial wealth?
If you were in your early twenties and starting from scratch, what would you do differently to maximize your chances of reaching this goal?
Are there any books, people, educational resources, or experiences you would recommend?
I’d especially appreciate advice from people who have built successful businesses, accumulated significant wealth, worked in private equity or investment banking, or have experience with philanthropy.
I know my financial ambitions are probably much bigger than the average person’s, but I would genuinely appreciate realistic advice, including criticism if you think my perspective is misguided.
Ultimately, I want to build something meaningful, become financially successful, and use that success to give other people opportunities they might otherwise never have.
