I don’t think that’s an accurate description of ACA [1], it didn’t lead to a dollar to dollar increase in premiums (share a citation if otherwise), and it’s a bit misleading to say it led to an increase in premiums because plans pre-ACA were effectively inaccessible to and lacking in benefits for impoverished people or people with pre-existing conditions.
[1] Here’s a brief description of ACA from Wikipedia:
> The act largely retained the existing structure of Medicare, Medicaid, and the employer market, but individual markets were radically overhauled.[1][11] Insurers were made to accept all applicants without charging based on pre-existing conditions or demographic status (except age). To combat the resultant adverse selection, the act mandated that individuals buy insurance (or pay a monetary penalty) and that insurers cover a list of "essential health benefits". Young people were allowed to stay on their parents' insurance plans until they were 26 years old.
