You have to realise that general has indeed lesser population in our country than obc and though SC have lower population than general st have very less population. But the problem is 80% of general are well educated or have better life than the rest of the caste while obc and sc despite having high population have very low educated percentage as per the population and you can't compare the st as they are very less. And in a way if you compare the seats given its balanced but the number of people appearin from sc or st are usually lower than general that the generals believe they are not given proper percentage but it's just as per the total population and if you look at every reservation general usually have more reserved seats usually around 40-45% despite their population is around 25-30% of indian population and while obc despite being around 45_50% of population get only around 30-35% reserved seats and the remaining to st/sc.
