A bill from Senator Chris Murphy to raise the federal minimum wage to $25 an hour is framed here as bad news for small businesses, with the argument that it would help big chains and hurt small shops.

• The federal minimum is $7.25; the proposal more than triples it to $25 an hour, about $50,000 a year.
• Big companies like Walmart and McDonald's can absorb higher wages because they buy in bulk and pass costs to customers; small shops in low-cost towns can't.
• A one-size-fits-all wage ignores that living costs vary hugely by state — income in New York is roughly double that of the poorest states.
• Higher wages push big chains to replace workers with self-order kiosks, cutting the entry-level jobs teens once filled.
• No state currently has a minimum near $25 — the highest is around $17 — so the plan is framed as a political distraction rather than a real proposal.

Outlook: The bill is unlikely to pass, and the bigger story is the Democratic establishment losing ground to its harder-left wing.
