This is prime agitprop.
The idea is that technology has developed so that everyone could *theoretically* stay 25 years old forever. However, everyone only has a certain amount of time (shown by a counter on their wrist), and if they run out they instantly die (for reasons that the film never explains). Time is used as both a currency and as a timer for how long people have to live, they pay rent with time, they buy food with time, they work for time, etcetera.
There are frankly monstrous levels of inequality and the film repeatedly makes the point the point that the system is set up to benefit those at the top and to limit social mobility at all costs (to the degree that a group of time-police turn up and confiscate all but 2 hours of the time of the main character, who's a working class guy from the slums, who got given over a century by a suicidal rich person who explained how the system was set up for the purpose of exploitation). The story says at various points that the titular capitalist makes nothing of value, and explicitly says "is it stealing if he already stole it?" in reference to them robbing and then distributing a time-lenders owned by said capitalist.
It also says that the main cop managed to pull himself out of the slums by making sure that no one else would ever leave and
It has loads of other stuff like that in it that I can't remember right now. All in all it's brilliant agitprop with the only exception being the bit where the main character gives the cop some time so that he'll just survive long enough for other cops to arrive and take him to withdraw some of his time from the bank or something (on the other hand though this is right after the main character's shot him in the chest and just before they steal his car and they make the point many times later that being a cop is scummy).
btw the film is also really horny so the two main characters are basically always either in really tight clothes or half naked (or entirely naked at one point).
