Starvation ... or the threat of starvation is what causes people to revolt.

As long as there is cheap readily available supplies of food ... even if it is terrible, barely affordable or complicated ... but people are still able to eat non-the-less ... there will never be a revolt.

The wealthy dangle food in front of the masses to just get them to hang on the edge but not so far over that everyone will riot and destroy everything.
