I've seen many times how difficult it is for small to mid-size businesses to compete against large corporations. There are various reasons for this – including disparities in terms of resources, knowledge / insights, and research. Large companies have had the advantage of building up their capacity over many decades, both nationally and internationally. It's often a struggle for smaller businesses to gain market recognition and have decent work conditions.
Typically, smaller businesses don't have the funds to pay their workers as well compared to the larger companies. They usually aren't able to provide the same quality work resources (such as technology, product support, and so forth). To me, it would make sense for all US states to agree on a sales tax on large corporations, and invest that money into subsidies for smaller businesses. Those funds could help the smaller organizations build up their operations, pay their employees better, and so forth.
