re: Who will pay for Trumps everyone to have healthcare?

What do we know as of now?

Nothing until the bill is explained followed by a repeal of ACA.

What's been reported or said by Trump:

1. Children stay on parents plans until 26
2. Pre-existing conditions stay as long as you have coverage prior.
3. Open the doors for multi-state bidding between insurance companies
4. Take away the fines for people who opt out.

How will we afford it?

The insurance companies may dictate this to a certain extent for small business owners and sole proprietorships, but larger companies will be able to lower rates and premiums. This is also goes for state and local govts that also seek the same things.

It can't be any worse than what we have as of now.
