I think this really depends on cost of living and tax. Going on a basis for the UK where I'm from, average monthly earnings before tax hover around the $2,000 mark (with current exchange rate). So $5K seems an enormous wage to me.  $60k per year sounds more than comfortable to me. However, we have the NHS and aren't paying out of pocket for tuition at university (to some extent).

tl;dr - It really depends, but $5k seems significantly more than comfortable from my perspective.

Well, an average restaurant/"unskilled" labor worker makes $20-30k a year.
People with degrees and in jobs like accounting, finance, etc make $40-70k as starters.

So for me personally I think the $4k-5k is a comfortable range (not a lot per se).

Again, that really depends on location/country etc. I'm assuming by restaurant you mean an actual restaurant, as opposed to fast food joint? I can't say I know anyone making that in a restaurant of any kind where I live - Not to say it doesn't happen, but that's a relatively high end salary for entry level work. However, restaurants tend to pay more than say an admin office job at entry level.

For example, at a company I work for, everyone below a management position earns $25k at an absolute maximum. At entry, they are barely above minimum wage. However, the engineers would be on somewhere between $30-$45k for their skilled work.
