Abstract: In private economies there are significant differences in income levels between the European Union

(EU) member states and a substantial proportion of the income inequality between the citizens of the EU can be

explained by differences in incomes from country to country. Of the EU countries, Lithuania has the lowest standard of

living, with an average equivalent income of 5,304 Euros, while the highest average income level (29,153 Euros) is

measured in Luxembourg. The former socialist countries cluster together at the bottom of the scale, with average

incomes of under 10,000 Euros. A capital investment is the acquisition of a fixed asset that is anticipated to have a long

life of use before it has to be replaced or repaired. Two of the most easily recognizable examples of capital investments

are land and buildings. However, a capital investment is made any time that a company purchases goods that will be

benefit the operation of the business, but will not be used to cover the operational costs of the business.

Keywords: economic welfare, capital investments, economic culture

1. Introduction

multifaceted economic research, taking into account the fact that the status of man in a certain period means

both a consequence and a prerequisite for economic growth and development over the long term. The

economic situation of people at any given time depends on the highest proportion on the size of the incomes.

The results of the population’s activity must be distributed fairly among society members, depending

on their social and economic interests.

Another aspect studied lately is the issue of poverty. With all measures taken, one ascertains that

poverty still exists and extends, having as its main source of generation and sustainment the way of

distribution and redistribution of income.

This inequality of opportunities is the result of the market, of competition and of the society

integration way.

Inequalities on income distribution can create incentives for people to improve their situation through

labor, innovation or acquiring new skills.

The evolution of economy entails in an organic way permanent distribution of income so it promotes

the development of the individual and the community as a whole, on the coordinates of
