If you have sufficient money, then a business can be a place to generate income ... generally, it takes a job to get that income or pawning your house. Few will do a private placement and raise funds through equity capital. Business that can be started with low barriers will soon be saturated, e.g., Bitcoin mining.
In essence your saying, those running a business without sufficient income won't be able to generate income from there operations?
That won't be accurate as I see a lot of them in my country running a table market just at the road side for those not able to rent a shop and display there business. I won't take it that I know much into the lives of these persons but from my rulings on most and the time they give to there business, you can tell its there sole dependency for survival and they ensure to manage it good.
Once you realise your business to be a separate entity from yourself, you site it in a good location of demand and manage it good, you'll be good too.
Some people are born rich and they have struggle less to earn money.
So are born poor and they keep struggling for the rest of their lives to meet their end. If you are born poor and die poor that is your fault - this also means that you have not struggled in the right direction.
