I am a high school student starting grade 11 this year. I am really not happy with education in India here so i plan to go abroad probably US for my undergrad physics degree.I also intend to apply to a US grad school for my Phd after my Undergrad work.So this whole will take about 7 years on avergage and i will be 23 by the time i get my Phd. So after i get my Phd if i get a postdoc at a university or any other organisation how much do they pay . I love physics and doing Physics but i dont want to be underpaid after 7 years of hardwork . I dont have any intention on marrying or having kids . So what kind of lifestyle can i ( only me without family , alone ) have with the postdoc level of salary .
