How can this nation progress without enough affordable housing for lower paid workers?

Run for local office in your state, VAA...It gives  you insight and power to make positive changes.  Here in Missouri you can rent a decent apartment or home for as low as $150 a month all the way up to over $1,000 per month---it depends on what you want.  We also have an uncorrupted HUD program that enabled my daughter and her two little girls to have a subsidized two-bedroom house in a small town for $24 per month, including utilities.  East coast and West coast housing is overpriced---consider moving to the Midwest.  

theres always low income housing

Lower paid workers used to strive to improve their  situation by getting more education. Seems like all they want to do now is whine, cry, and expect the Government to give them a free ride.

In some cities like Seattle and San Francisco, only people earning a six figure salary have any chance of home ownership.  The working class in those cities simply needs to move somewhere more affordable.  Many large cities in Texas have affordable housing.

Put-up a tent on a sidewalk; same as L.A. or San Francisco, huh?

It can’t. Even Slave Owners provided their slaves with shelter.

Nobody seems to be trying. Its greed and it is getting worse. Soon we will all end up in the desert like the Indians.

Deport all illegal aliens. 

Citizens require more money and can live independently.
