Being Canadian, I have access to public health, but if I get sick with even minor things, it'll take up my whole day. Now, if I get sick, I'll just pay the ~$200 fee to see a private doctor for 15 minutes, get what I need and get out.
Dental is not covered by public health, so there were at times I delayed treatment because I couldn't afford it.
I used to live in Vancouver where people will tell you they have good public transport but it's a lie. It's really only if you live along the skytrain corridors because the busses are always late and it's always raining. So if you don't have a car, you're wet, cold, late, and miserable. Now I just pay for Uber. Better yet, I just live downtown and I can walk wherever.
Going to the grocery store when I was poor was also difficult. Thinking about what I can afford means spending time comparing prices or even stores, and compromising on the meals I wanted to make. Now I just throw everything I want into the cart and I don't even look at the price tag.
Being poor sucks and there are countless more examples.
