US: + once you finish education, and if you start employment in tech sector, you get to make more money(I’d even dare to say more than 2x, considering taxes, geography etc).
+ for the tech sector, US is where the hotness is. More opportunities, fuel for ambition.
+ while single and young, US can get you a lot of disposable income(read - less likely to get sick footing a huge medical bill, or avoid expensive child care, or school fees of children)
+ language. You don’t need to spend your time learning a new language that you may or may not use in the long term.
- (cons)
- politics (depends on personal views of course. Ask yourself if you can bear a society in which Trump wins the elections)
- the odd chance that you get in an accident or get sick with a weird/expensive disease, you’re screwed.
- personal opinion - food, lifestyle, and quality of life is comparatively poorer in the US on average than in EU. Read obesity, fatty, ultra-processed and sugary foods.
- Geography - farther to South Asia than Europe.
- Guns (depends on your views)
EU:
+ Safer, more consciously biased towards better quality of life. More public transport, walking cities, higher quality super markets, and produce etc.
+ politics (left leaning compared to the US on average)
+ traveling and cultural diversity - as in you can travel across the continent as even weekend trips and experience rich and diverse cultures - Italy, Spain, Germany, Austria, Poland, Netherlands, Scandinavia, France - so many experiences to be had.
+ in the long term, you don’t need to be anxious about falling sick, losing your job, education for your children etc. Social system has your back for all the taxes you pay.
+ Easier and probably cheaper to travel to South Asia often.
+ You get real holiday(atleast. 4 weeks or upto 6 weeks per year) to travel and live your life while young instead of bunkering to earn money.
- you definitely won’t make as much as you would have in the US.
- language. Depends on where in Europe you go, you may need to spend considerable amount of time learning the language. It could be a fun experience depending on your attitude, but it is time nevertheless.
- lowered ambition. A personal opinion. Having living equal time at both US and EU, I’ve come to conclude that EU encourages stability and playing it safe while US encourages ambitious attitudes and gets the best out of you. It depends on what you are looking for, and what you enjoy.
Hope it helped atleast a little and didn’t add more dots to your analysis paralysis.
To tip the scales, I live in the EU.
