Walmart's idea of health care is to post the phone number for the public aid office on the bulletin board. They like making the local communities pay for everything.
One of their standard tricks is to promise the local politicians that they will bring in lots of jobs, but in return they want the local municipalities to excuse them from paying property taxes for 5 to 10 years. And they want the municipality to install all the water and sewer lines and their drainage system. The local politicians go for this because they are usually cronies of the local construction companies that will build the store, and they can blow smoke about bringing jobs to their community. So the taxpayers buy Walmart their water, sewer, and drainage systems, and give the them a tax exemption for 10 years, and then when the tax exemption period is up, Walmart moves the store a mile down the road and they do it all over again.
Meanwhile they drive all the local store owners out of business by undercutting their prices (losing better paying jobs for the community, and siphoning off millions of dollars that used to stay in local circulation), while they make the local people who owned those businesses pay for Walmart's water, sewer, and drainage systems.
And for all that the jobs they create are so low paying that their employees still need food stamps and medicaid to survive. Which the community also has to pay for.
