I'm toying with the idea of finishing my undergraduate degree and then entering industry for a short while. If I spent three years and earned enough, my thought is that I'd soften the burden on my parents of financing the sinewy road -- filled with costs and time -- I'm willing to take in earning a PhD. If I earned enough after three years, then I'd feel uninhibited, for example, in getting two masters, waiting another year to apply for a PhD if I were rejected the previous year from one, taking a year off to research and so forth.
Spending a few years to earn money seems good, except that during these years, it's dubious whether I can work towards making myself a stronger graduate school applicant (most importantly, by doing more research). Also, any research done as an undergraduate would, I fear, go to waste. If I returned for a masters at my undergraduate institution directly after finishing my undergraduate, by contrast, I could continue whatever I was working on as an undergraduate.
A possible remedy is to research on my own (or under a willing professor's supervision) while I work in industry? Have others tried out such plans? Are they generally advisable?
Please Note: My question is different from the suggested duplicate, because I ask about the possibility for a student (and not a PhD) to perform research on the side (after working hours) while working in a non-research role. The duplicate question resolves whether someone employed in some company's research division can also research themselves independently.
