This is subjective to the job you are talking about, there are still offline work that paid more than online jobs and the top 10 highest paid jobs on the list doesn't have online jobs included, they are all medical fields, surgeon pricely and this is because the rate at which people undergoes surgery is alarming, people now want every part of the body to be adjusted and perfected because they feel they want to be extraordinary people and more fit to the society and because it has to deal with life, the job require high pay to keep up with the demands from patients that want the surgery.
Software engineers is one of the first job that paid much for an online job list in my research and they are well paid because designing a software is kind of a job that require all half of your life, you need to be there and must be security conscious and that's why a cyber security and software engineers are well paid in there jobs.
then you could work remotely or doesnt really need to go to office every single day which you are doing on offline but we know that not all would really be given out opportunities when it comes to getting jobs
despite on having a good educational background offline due to high competition then this is the reason on why they would really be touching out online world on trying out to apply for jobs on which they
could potentially be able to hire up themselves when it comes on being chosen but still competition is there or cant really be that removed out.
Everything would really be basing or depending on your skills because even if we do say that earning online is something better but getting one or getting hired isnt something that would
be simple neither, you would really be still needing to prove out that you would really be that competitive compared to others.
