"Enforce minimum wages that people can actually live on. Most poor people work significantly harder than your typical white collar office worker. The only thing that separates most of the middle class from the poor is that the middle class had a solid foundation from their family on which to build their future."

What would stop companies from increasing the costs of their goods and services because they know minimum wage is higher (and people can now afford it)?

Minimum wage in the US is $7.25/hour (many states are higher). A person couldn't support a family on this, but they could find a place to live (either renting a room, cheap apartment, or sharing a bigger apartment with friends) and have enough left over for the bare-minimum.
