So your insurance is paid by your employer in full? The place I work at doesn't provide insurance for anything extensive. Point being that it's unfortunately not everywhere.
You can't have free healthcare only for people in poverty... that's too impractical. Just wouldn't work. It's either all or none in that way to me.
Honestly, though, do you know the value of $2500? If you live on $20,000 a year (yes, I know that's low, but not by much), that's more than a month of your pay. If you, combined with paying for rent or utilities, insurance, food, clothes, A FAMILY, etc. etc., $2500 is a ton of money, probably more than you're able to save throughout a year. And that's on your insurance plan, which is essentially covered completely.
If someone has to pay $150,000 for eight operations in order to remove tumors like someone in my family and live on $20,000 - hell, even someone in the middle of the pack around $50,000 - you're completely screwed.
