How do you define socialism, then? Does that automatically follow that since a country is providing free healthcare, education, and other social services to its people it is already a socialist country? How about the fact that capitalism and democracy is actually very much vibrant in the European countries that you've mentioned like France and Norway? Or is it that both capitalism and socialism could exist side by side in a government?
The essence of socialism is very simple - steal the money from the successful people and distribute a part of it among the poor. Since the poor have a greater voting power, the political party which promises to do this will be elected to power very comfortably. Now the problem with Socialism is that, eventually they run out of money to steal from. Successful people will either migrate to other countries (similar to what happened in Cuba), or they will lose their money and become poor themselves.
And the worst part is that they never listen, if a socialist country wants to raise taxes that is one thing, but in Venezuela we saw the government confiscating the assets of big companies, the international community warned the government of Venezuela at the time this was an awful idea as no one will want to make business with them in the future if they kept taking those actions.
They did not listened and now they cannot attract foreign investments, they thought they could get around this with their oil income but when the price collapsed this threw into disarray any semblance of order in the country and now they are going through these adverse times, and unless something changes this will be their reality for decades to come.
