I agree it isn't enough. I want UBI and Medicare4All and post-secondary education (including trade schools) free to accepted students, and so much more.
But, I will gladly take a federal minimum wage increase. I do think it should be set based on cost of living in the cheapest/poorest states, and that some states should have an even higher minimum wage.
(I would not directly benefit, I'm currently unemployed, but generally paid significantly more than minimum wage [I'm a computer programmer by trade.].)
No. It would probably be better for it to come in incrementally, but increasing wages would help, even if it might squeeze some small businesses. Having looked at the balance sheet for more than one small business, wages are rarely the most significant cost, and when they are the profit margins are larger.
Every time the minimum wage increased while I was a kid, my father (a small business owner) complained, but the county got better overall. Any business that closed was replaced with two that provided the same goods/services within 6 months.
If you look at the data from states raising their minimum wages, you won't see either massive price increases (some, tho generally tracking inflation) or a large decrease in small businesses per capita.
