The ACA has some big holes; part time workers (even those who work multiple part time jobs) were not included in many of the best parts of the program, and there are “doughnut holes” that have left some people in a worse position than they were before the act. However, these holes were made even bigger by Republican opposition. And any attempt to stitch the holes was also blocked by the Republicans just to see if they could use it to tear the fabric of this country. They did, it worked, and now we’re likely to end up with something much worse.
Republicans will replace the ACA with something that gives people the appearance of coverage, or at least the appearance of “access,” and which may even appear to have lower rates. But it’s a zero sum game and the result will be that people will have less coverage, higher deductibles, and almost certainly be removed from the expanded Medicaid program.
As for your family’s perspective on welfare, there’s some things that they need to understand; welfare as it is generally understood was essentially ended under Reagan. Food stamps are far and away the largest government assistance program, and can only be used for food. The second largest program is unemployment insurance, which isn’t welfare at all - it’s a program that people pay into when they’re employed, and which they collect for a very limited time if they get laid off (not fired, btw) and there are limits on the amount that a person can get. There’s TANF which is a temporary program for families in need.
The biggest problem this country has is with part-time employment. More than 50% of the workforce is unemployed or underemployed, and many people work part-time jobs which offer no benefits. About 20% of the workforce is on food stamps because minimum wage is not a living wage, and companies (like walmart, notoriously) essentially use the food stamp program as an excuse not to pay their workers more. The food stamp program is a subsidy to corporate america. We could fix many of the problems (and significantly reduce the cost) if we made employers pay in to a fund to cover their part time workers, based on that worker’s number of hours worked - essentially require part-time employers make an equivalent contribution to health care as full-time employers have to make. This would actually create a surplus in the fund, since about 1/3rd of all part time workers actually work multiple part time jobs.
