I think the major problem is when companies go public and have shareholder money they tend to maximise their profits at the expense of both the customer and the employee.
The employee will never feel the same way the founder does for the organisation as they don’t have much skin in the game as the former does. So it’s kinda weird how they expect them to put in the same dedication especially when the culture becomes toxic day by day.
The final issue is how the senior employees especially the ones who are the management lackeys pay no heed to what their subordinates tell them and the cycle keeps continuing which means this loop will never end and the rat race will kill you before you even start.
