I strongly agree with your opinion, we cannot blame for these reasons, getting married, paying taxes, using banks, all the basic and indispensable needs in the life of each people,
if we do not follow these rules, we will be rejected by the society in which we live, complete all this work, we can still be rich when so many successful people clearly show these things. While examples of wealth without marriage or without paying taxes and without using a bank,
the odds of appearing are too low and often stick to the law, getting rich not too long
If you dont pay taxes, your reject, your dont get married, your rejected, you dont use bank, your rejected, your dont invest, your rejected, you dont get a job, your rejected. You bypass the law, your rejected.
I don't think this idea is bad, but I would strongly advise you to think about this issue again. People live, they need happiness, love, why must be rich while happiness is not, live in poison. Getting rich by breaking the law, I quite like to bypass the law, but the fact that a citizen does not pay taxes, other benefits are difficult for you to benefit, you can say that you are a freeloader of the country.
Nope, there is no laws breaking in doing this five simple steps,
Dont pay tax: there is no laws protecting one must pay taxes, NONE!!!
Dont get married: no laws state one must get married! No laws is broken to not get married!
Dont use bank: again, no laws breaking! What law do you break by not using bank?
Dont invest: do you break the laws for not investing?
Dont get a job:

? Not getting a job is also breaking a law??
