Having two jobs at a time means that you've also taken away another job that should be for others. Just imagine if you hadn't taken that other job, someone would be taking it, and again, it helps them a lot. I don't mean that it is greed as we are just surviving, but it is really better to give it to someone as they also needed it. But again, I can't blame anyone or even myself as all of us struggle and one job is not enough.
Drinking is good if you are just taking it rarely, but doing drugs is not good, so never do it. I am into drinking once a week or once a month, depending on my health and my money; it helps me relax.
I would guess that it depends on the quality of the worker. If you take two jobs at a time and you do a better job then you are entitled to it. Think about it this way, if one person does 100 level work in 2 jobs, and 150 level work if they worked just one job, then I would guess that if someone who can do a 50 level job there, why would they get the job just because the other guy already has one. If he deserves the job then he deserves the job that's it.
I believe that in this day and age people should have two jobs, or a job that is basically open for more earning. For example I could work as much as I want and earn accordingly at my job, but if it wasn't like that and I worked at a job that had set amount of earning and that wasn't enough, I would look for a second job.
I agree with this because regardless of anything when we are in the position of a worker then indeed we inevitably and must be ready with all the competition that exists because basically our leaders do not want the assigned tasks to fail to be done so it depends on your readiness.
Regardless of 1 job or 2 jobs at once as long as it can still be done well then why not.
As for when this is said to snatch the jobs of others who need it, in this case it goes back to competition because of course if you fail to compete then it is not the fault of the person who can do 2 jobs at once but other people who cannot do better.
In this day and age I think competence is important so if you don't want your job to be snatched up by others then don't let your qualifications decline so that you will still be considered and in the end when you are displaced by others whose work is better it doesn't mean we have to blame others but blame ourselves for not being able to work optimally and losing the competition.
