Was doing some brainstorming and had an idea

What would happen if we installed massive tariffs on ALL imported goods and greatly increased (think tripled) the federal tax of transportation fuels.

I know that most people think economic depression would follow.. costs of goods would go up, prices would go up, sales would go down and the economy would grind to a halt. I think that is the conventional thinking anyhow.

But I'm wondering if something different would happen..

What if companies who still had a base here, suddenly found themselves in a position to now be competitive. What if they had to increase employment to keep up with the new demand. What if people had to live closer to the places they work and play.. new infrastructure and community building. What if it become too expensive for tax payers to subsidize big companies by maintaining highways for them.. and they had to actually pay their own way. What if those big companies decided it was cheaper/more cost effective to build more smaller plants then one large plant and ship everything. What if this resulted in our economy become self-sufficient again and we stopped making other countries rich.
