$5 a day is a significant amount of money to a huge number of people.
In the UK, if you're on minimum wage, a 3 quid coffee represents approximately 5% of your daily income.
If such an individual (someone who earned minwage for a lifetime) were to end up with even "merely" 100K in today's money at age 60 that would actually be an enormous amount relative to their cohort.
So 60 pounds a day is minimum wage in UK? It seems to be very decent middle class income rather than minimum wage. Or maybe you meant 50%?
This is pre tax.
If it were 6 GBP/day you'd get 120 GBP a month (pre-tax). That is extremely low. Living with so little anywhere in Western Europe would be very challenging, if not impossible.
I mean, stingy food shopping at Tesco for basic stuff four times a month would land at (guesstimating) around 10..15 * 4 = 40..60 GBP. This means eggs, bread, butter, vegetables, chicken, yoghurt etc. and no tobacco or beer. This estimate is probably too low as I did not count in soap, toilet paper, toothbrush/paste etc.
Likewise, the minimum of 1260 GBP/month in UK or Western Europe is not a lot, but I guess enough to get by somehow.
I am curious, what do you think is a high income in the UK (or Western Europe in general)?
60 pounds a day for 20 days is 1200pm. That is to say, it is impossible to rent a basic small flat and you will have to live with housemates or family.
Even having done that, transport and basic food will suck up all of the rest of your time and money.
It is by no means a 'very decent middle class income', in most of the South East it's poverty level.
6 pounds a day would be utterly comical, I'm not sure if this is a troll, I doubt that would be liveable in cheaper parts of Eastern Europe.
