How to get out of the middle class lifestyle

I am a fresher earning roughly 1 cr post tax. I started investing a little late but I am now consistent with my SIPs which I started at the age of 8 by saving 500 a month of my school bus fare and pooling a ride in my father's car with a step up of 10% every year. There was no driver so that we could save some money and put it in a fixed deposit every year.

I stay at my home so that I can save some rent. I don't get the privacy that a fresher looks for because my family is mostly out of the country and I had to get 24 hrs house help. But I am okay with it. Nobody gets everything.

Now I am paying around 48 lacs as income tax. What am I doing wrong and how to spend money wisely. And how can I make sure that I get paid according to the market standards and not get exploited by the system.

PS: is buying a new iphone 15 worth it as gold plated iphone 15 pro max is very costly.
