Isn't it a lot cheaper to split rent with someone else who lives in the same bed as you? And to cook for two instead of one? The way I see it, the only way being single is cheaper is if you live with family for free.
And moreover - finding someone you really love and care for and want to move in with is hard even when you're rich. Just look at all the dating sites and services catering to matchmaking for the very wealthy.
We might say --> the less time/money you have, the harder it gets. And when all your time is going to career + you're in debt... it's a bad combo for the dating pool, for both sexes.
I don't have any income, but I do have debt (including unpaid rents for when I lived away from my parents, in a "startup boom city"), I need expensive medicine (about 100 USD month in a country where mininum wage is 300 USD), who do you think is paying for all that?
It is not the government, because I don't even get unemployment benefits, because I was never employed legally in first place.
