"If you work at a large company you need to work for a longer time to have enough cash" <-- how long you need to work to have enough cash depends on two things:
A) your spending rate
B) your earning rate
And in general, your earning rate is faster at a company. Again, you have to compensate for selection bias here: not all startups are successful. Even if they are large enough to have employees.
Regarding your comments about little time, I think you are confusing "no free time" with "no free time at work to focus on something else". I'm definitely not arguing that people who work for startups dont have time for partying. Definitely not. All I am saying is that, because the nature and frequency of demands is different, you generally find yourself with more time to explore your own thing at a large firm. And yes, this is coming from a person in finance, so it must be true for other industries as well :)
