If I understand correctly, if you invest in a business you own, you own the money and you've worked for it, depending if you work in your own business or not. Spending government money you're being put into debt, spending money you do not own and soon will need to pay off. Either you've worked for your money, or you've borrowed money that you'll soon need to pay off, you're still working for it.
or
If you own a business and you need to pay for the water bill for your business you can either pay the bill with the money you've earned from that business or you pay for the bill with the government's money, which soon you'll need to work off the debt. Either way you'll still need to work for the money.
Sorry if this is wrong, I'd ask a teacher or a parent before using this, hope this helped some! I'm not the best in this subject, but my father owns a business so I know some about it so I thought I'd take a shot. (:
